Startup #6: – the AirBnB for bikes

Have you ever been in a city and wanted to make a bicycle-tour? Then you will probably be annoyed by the high prices and the shabby bikes. Time to change this with my next weekly startup: - the AirBnB for bicycles.

As always: If you want to read the summary first, here you will find it.

Day 1: Sharevent-Hangover and idea picking

My head still aches…at this weekend I finally had my Wine-Tasting from my first startup Sharevent.

It was a full success! Thanks to Tvino and the Makerhub, we had a wonderful evening, with 25 people and 13 different wines. It ended at 2 a.m. (at least I think so…) and it was a lot of fun. People got drunk and I got in touch with new, friendly people.

And of course people posted it on Facebook…

I made 825,- Dollars in revenue, but 0,- in profit, because I spent everything on the evening. Well invested money icon wink Startup #6:   the AirBnB for bikes

Stop drinking and start thinking

Okay, enough said! Time to start the next weekly startup.

Within the last week I generated over 70 new business ideas, therefore my first task for this week was to separate the good ideas, from the bad ones (and the really bad ones). I cut down the list to 8 startups, which I want to start within the next weeks.

I took the first startup on the list and started: (yeah, the domain was still available – i couldn’t believe it either).

The idea of

The idea of is fairly simple: I wanted to create a platform where people could offer their bikes for rental. It’s like AirBnB but just for bikes. People like to explore cities with bikes but most of the times you can just rent shabby and expensive bikes from greedy companies – why not rent stylish and cool bikes from private persons?

Here’s how it should work:

My biggest 3 problems

Okay, I have to build a so called multi-sided platform (MSP), where I could enable interactions between the demand and the supply side.

Puuuh, sounds horrible - especially for a guy, who has no real coding-skills, like me. icon sad Startup #6:   the AirBnB for bikes

I wrote down my 3 biggest problems I had to solve for to keep me at least focussed.

  • How do I build this multi-sided platform?
  • How could I get people to put their bikes on my platform?
  • How could I get traffic to

This will be my workload for the next 4 days. Sigh icon wink Startup #6:   the AirBnB for bikes

Day 2: Building the website of

Yeah, I know what you think: “This guy always says ‘Don’t build websites – build businesses!’ and now he is building what? A WEBSITE! Seriously?”.

Yes, you are right. Of course I could try to do everything without a website (using email, phone, Google Forms etc.). But in this case the (basic) website was very easy to build and I thought it was easier to remember then my phone number. Therefore I wanted to give it a try.

Defining the target customers

Before I started with my website I took some time to define the target customers. For the demand side I assumed that mostly people on a vacation would use my service. For the supply side this was a little bit tricky: Whom should I ask to rent their bikes on

I wrote down the characteristics of my “supply side target customer”:

  • Interested in a small additional income: Probably you won’t get rich, when you offer your bike on Therefore the target customers must be interested in even a small additional income.
  • Owning a bike: The target customers must own a bike – makes sense icon wink Startup #6:   the AirBnB for bikes
  • Close to the city center: The target customer should park its bike close to the city center, because that’s where the “demand side target customers” (= tourists) are

It really took me some time to find the right “supply side target customer” but then it suddenly hit me: Students! They always need some additional money, most of them own a bike and universities are very often close to the city center.

My fellow students, here I come!

Using WordPress to build

With my target customers in mind, I started to build my website. I used WordPress and the awesome Enfold theme, which I used for some other websites before (I really, really love it).

It took me 4 hours and 15 minutes to build Because I didn’t have the time to build an automatically working multi-sided platform, I decided to use some manual workarounds for most of the processes.

workarounds for MyBikeRental Startup #6:   the AirBnB for bikes

In my opinion it is always a good idea, to program functionality when you really need it – and not in advance!

Preparing customer acquisition

Tomorrow I wanted to visit Hamburg’s university and hand out some flyers. Time to prepare the stuff!

I decided to use the following text (I put my comments in [...])

“[Address customer] You own a bike?
[Get attention] You want to earn some extra money?
[Explain the idea and make it a no-brainer - that's why I added "during the lecture"] Then why not offering your bike during your lecture for rent?
[Call-to-action] Sign up at today!”

That’s it. I wanted to keep it as simple as possible. I added some nice graphics et voilà!

Flyer MyBikeRental Startup #6:   the AirBnB for bikes

Off-topic: How to cut out flyers fast

At my last startup Checkout +1 I got crazy, when I cut out all the flyers with a scissor. Therefore this time I tried something new: Knife, Chopping Board & Ruler! icon smile Startup #6:   the AirBnB for bikes

How to make flyer fast Startup #6:   the AirBnB for bikes

I know it’s a little bit off-topic, but using a knife, a chopping board and a ruler instead of a scissor is much, much faster. And this is the best way to do it: Start with the inner borders first and then finish with the outer borders.

Lessons learned

These are my lessons I learned from day 2:

  • Build functionality when you really need it: Try to do most of the processes of your website manually – just build functionality when you really need it.
  • Define your target customers: Before you build a website define your target customers. It helps you to stay focused on the things your customer really needs.
  • Use knife, chopping board and ruler instead of scissors: Don’t use a scissor when you want to cut out flyers. Take a knife, a chopping board and a ruler. 

Day 3: Handing out flyers at the university

Time to get up and visit my old university! Time to hand out some flyers!

Double check the website

Before I started to hand out the flyers I double checked my website

This is an advice I give everyone who publishes a website: Build the website, sleep a night and then double check it. Even small mistakes (like wrong phone number) can have a big impact (all the people you gave a flyer couldn’t reach you) on your business.

Getting out to hand out flyers

I went to the university and there I went directly to the canteen.

Canteens are a perfect place for flyers. Why? Because people (especially students) like to read, when they eat. There I was at my old university, putting 80 flyers on tables in canteens. Weird!

hand out flyers at university Startup #6:   the AirBnB for bikes

Unfortunately I made a mistake at the flyer-design: They were too small! Therefore it was very hard to recognize them between all the other flyers.

Note to myself: Don’t save money at the wrong place and make your flyers BIG!

my flyers are too small Startup #6:   the AirBnB for bikes

Results, Results, Results – Checking the numbers

It’s 10 p.m. – time to check the results of the flyer campaign. I went to my Google Analytics account and checked the number of visits. Here is what I saw:

google analytics mybikerental day1 Startup #6:   the AirBnB for bikes


2 users? Actually it is just 1 user, because I was the other one…THAT’S disappointing!

But here is the good news: Guess my conversion rate? It’s 100%. Yeah, the user who visited my website registered for That’s great!

It seems that I got a problem with my marketing. Putting too small flyers on university canteen tables didn’t seem to work. I have to try something new, to get more attention.

Lessons learned

These are my lessons I learned from day 3:

  • Double check your website: Before you publish a website, sleep a night and then double check it.
  • Do it right at the first time: Don’t save money at the wrong place. Chances are high, that you have to do things twice, when you don’t do things right at the first time.
  • Track your website with Google Analytics: That’s a no-brainer, but I think I never mentioned it before.

Day 4: Better flyers and AdWords

Okay, I need more attention for Perhaps I should ride on one of these high wheelers, wearing a big top hat and scream out loud “RENT OUT YOUR BIKE”. Or perhaps I should do something else…

Building better flyers

Forget the high wheeler idea. I will build better flyers. icon wink Startup #6:   the AirBnB for bikes

Short analysis: What went wrong with my last flyers?

  • They were too small
  • They were not very eye-catching
  • Wrong place: Putting them on tables in the university canteen didn’t work out

But there were actually one thing that was really great about these flyers: I could produce a lot of them with relatively small costs (I printed 8 flyers on one sheet of paper).

Therefore I did a redesign of the flyers and this is what came out:

new flyer MyBikeRental Startup #6:   the AirBnB for bikes

These are the changes I made:

  • I made the flyer much bigger
  • I used a big image and red color to make it more eye-catching
  • I used 9 tear-off stubs (don’t know if this is the right word for the things at the bottom), so I was still producing a lot of “flyers” at a relatively low cost
  • I changed the message a little bit. Now it says: “[Headline] For rent! [Subheadline] Cool bike for just 10,- € a day! [Text] You can do this too! Rent your bike on and get some extra income. Sign up now for free!”. My idea was, that this twist in communication made my advertising more interesting

Better distribution for my flyers

I went back to the university but this time I changed some stuff.

I decided to display my ads where cyclist would see them. In other words: I tried to reduce my waste coverage.

So I put my ads on traffic lights (actually I don’t know if this is legal) and on bicycle stands.

I am curious how this will work out…probably I will get into jail.

An even better idea for getting customers

When I was at home I got an even better idea how I could get customers: Why not taking a picture of a bike and then put a note on the bike, which says:

“Hey! I would like to rent out your bike at You could make around 10,- € per day by renting your bike to a private person, who would love to do a city tour with your lovely bike. You just have to visit and sign up for free. We already took a picture of your bike, so most of the work is already done!”

This would make the sign up process much easier for the customer – and of course people would visit the website to find out if I put a picture of their bike on it (which I would not do, of course).

Building an AdWords Campaign

I haven’t done anything so far, to validate the demand side of my business model. Therefore I decided to build a quick & dirty AdWords campaign to get people to my website, who would like to rent a bike for a city-trip.

adwords mybikerental Startup #6:   the AirBnB for bikes

I gave it a small budget of roughly 15 Dollars, because I just wanted to test it. Let’s see if people would rent a bike.

Lessons learned

These are my lessons I learned from day 4:

  • Focus your ads on your target customers: Handing out flyers to everyone does not make sense, handing out flyers to people who have bikes is much smarter.
  • Make it as easy as possible for your users to sign up: Take the work out of your customer’s hand and do most of the work on your own. I should have taken pictures of the bikes, not the customers.
  • Give your users a reason to visit your website – make them curious: If I would have tried the “I made a picture of your bike” idea, probably more people would have visited my website. Why? Because people are curious and want to find out what I have made with the picture.

Day 5: More traffic – at least a little bit

Day 5 – final round! Did the new flyers perform better? Did the AdWords campaign work out? I will make it short: Yes, but on a very small level.

New flyers = more traffic

The new flyers work a little bit better. I could increase my traffic by 100%.

old flyer vs new flyer1 1024x231 Startup #6:   the AirBnB for bikes

It’s not as much as I hoped for, but at least people are reacting better to my new flyers. Bad news: There were no new signups. icon sad Startup #6:   the AirBnB for bikes

Did AdWords worked?

Yes, it did. I got 20 visits in 2 days via AdWords and one visitor signed up to rent two bikes for 2 days (unfortunately I had to reject him, because I had no bikes available). Again: That’s not much, but for doing this business on such a small scale, it’s quite okay.

Is this good or bad?

Well, is MyBikeRental a success or not? Let’s have a look at the numbers.

The demand side

I am very confident about the demand side.

It just took me 20 visits to sell 2 bikes, that’s a conversion rate of 10%. Of course I know that there is not statistical significance, but when you build a startup its hard to get something like this. Sometimes you have to go with your guts: I get a good feeling about this.

The biggest problem I see on the demand side is the potential: There are just too little number of tourist in Hamburg, Germany (that’s where I live and tested Giving you an example: Hamburg has 5 Mio. tourists per year, San Francisco has 16.9 Mio. tourists per year, New York has 47 Mio. tourists per year (sic!). You see what I mean?

The supply side

I am not as confident about the supply side as I am about the demand side…

The biggest challenge on the supply side was getting attention. But I am very confident, that you could raise the attention level by a more “aggressive” marketing (making pictures of the bike and putting notes on the bike). And I am very sure, that in a more touristic area, people are more willing to rent out their bikes, because they see real-life examples (= real bike rental businesses).

It was some hard work to acquire one supplier – but it worked. And it worked with a really shabby website. I think, when you would build an app or a cooler website, you would get more signups.

Conclusion: Success or Failure

I am more on the success side, because I have a (very small) proof of concept. I really would like to try out in a more touristic area, to get a more realistic validation.

Summary: Here’s what I’ve learned from startup #6 works, if only on a small level, but it works. I think that Hamburg is probably not the best place for such a business, because it is not touristic enough. But I honestly think that this business could work in tourist areas (I just think about all the “Rent-a-bike” companies in San Francisco or New York).

So, if anyone of you live in an touristic area: Try it out! Write me an email, I would love to help you (and I have a domain to sell icon wink Startup #6:   the AirBnB for bikes ).

Well, here’s the summary for startup #6:

Elevator pitch: The startup idea in one sentence – The AirBnB for bikes!
How did I get the idea for the startup? I used the “Solve Your Own Problems” tool: At my last holidays I was annoyed by the high prices at bike rentals.
How did I try to make money with the startup? I wanted to build a multi-sided platform, where people could rent bikes from private persons. I would take a commission on each renting.
How much money did I make and where did it come from? Zero – but it wasn’t my first goal to make money. I wanted to find out, if people would use the platform.
What decision did I make after one week? Grow or go? I really like the idea and I was impressed, that it worked – if only on a small level. Probably Hamburg, Germany is not the best place for such a business. But I think the idea could make some money in a more “touristic area”. So, anyone want to try? icon wink Startup #6:   the AirBnB for bikes
What were the main learnings of the startup? How will I use them for the next startup?
  • Build functionality when you need it: Don’t do everything at once, do things step-by-step. Most of the functionality of your website you can build later. Focus on validating your business idea.
  • Make it as easy as possible to sign up: Do all the work for your customer. Next time I will try to think “How could I build my offer in such a way, that the customer just has to say ‘yes’ or ‘no’.
  • Give your users a reason to visit your website – make them curiousGive people a specific reason to visit the website. Make them curious. Try to connect their life’s with your website.
  • Use price tags: I think it is smart to say to your potential clients how much they could earn, when they sign up. Saying ‘You will earn some money’ is not enough – saying ‘Earn 10 Dollars extra per day’ is better.
  • Do it right at the first time: Don’t save money at the wrong place. Chances are high, that you have to do things twice, when you don’t do things right at the first time.

    Hi Chris,

    you are right – the prices (for renting) are too high.

    But as far as the supplier is concerned–>don`t you think that an insurance would increase the confidence in your service?

    Kind regards

    Hi Chris,

    Great post again! The funny coincidence is that I met with a couple of entrepreneurs last monday and we actually had the same idea!
    There is already a car version of this in the Netherlands, but it doesn’t really seem to take of. Perhaps people value it too much to rent it out. I also think Elmar has a good point regarding insurance, since bikes get stolen a lot.

    Have a nice weekend and good luck on the next startup!

    Hi Chris,

    imho you didn’t thought this through enough. ;)

    1. You missed customer validation. Would people really rent their bike to someone? Especially for students their bike might be one of their most important items. They probably wouldn’t like to lose it.

    2. I’m not sure, if your tourist count is correct. In 2012 Hamburg had over 10 Mio. hotel room bookings. I guess, you could easily add one or two million visitors who didn’t sleep in Hamburg. Just think of the “Hafengeburtstag”, which – of course – is not a good weekend to ride a bike. ;)

    3. Hamburg already has a good bike rental service. The bikes might not be the best, but there are a lot of stations in the city, where you could get and – most imporant – leave a bike. So it’s very easy to use.

    Great stuff Chris! I like you style of ‘Screw it, Lets do it’ instead of sitting around with ideas!

    SUPERGEIL CHRIS! Mit solchen Ideen kommt auch Hamburg als Gründerstadt nach vorne.

    Ich habe vollen Respekt vor der Leistung, die in der Umsetzung steckt.

  6. Christopher Reply

    Ich finde die Idee echt gut!

    Der Service könnte bestimmt auch in Hamburg funktionieren, ich bin oft beruflich dort und würde den Service pro Woche ca. 3 Tage nutzen wenn gutes Wetter ist.

    Vermieter / Bikes könnte man wahrscheinlich recht gut über Flyer als Anhänger am Lenker gewinnen (sowas:

    Für die Übergabe und das Mietmodell würde ich einfache Zahlenschlösser verwenden und nicht zu viel Aufwand treiben. Als Übergabepunkte würde ich die großen Bahnhöfe, den Busbahnhof und den Flughafen wählen.

    Eine Versicherung für die Räder dürfte ca. 20€ pro Jahr und Bike kosten, natürlich abhängig von der Stückzahl und den Mietvorgängen.

    Als Zielgruppe würde ich mir zusätzlich auch Fitnessbegeisterte auf die Fahne schreiben um den Gesundheitseffekt stärker mit reinzubekommen.

    Neben der Vermieterprovision würde ich weiteren Umsatz durch Services (z.B. Bike steht an einer bestimmten Adresse bereit) und Produkte (günstige Helme und Beleuchtung) generieren. Außerdem könnte man von den Bikebesitzern verlangen das die Bikes der StVO entsprechen und ggf. ein entsprechendes “Mach dein Bike fit” Paket anbieten.

    Beste Grüße

      Hi Christopher,

      vielen Dank für den Super-Kommentar!

      Sehr cool finde ich die Idee mit den zusätzlichen Service-Leistungen. Bin ich mal wieder gar nicht drauf gekommen – aber das kann wirklich noch einmal ein Hebel sein.

      Würdest Du die Fitnessbegeisterten dann mit speziellen Fahrrädern “beliefern” wollen, also Rennrädern etc.?

      Liebe Grüße


      • Christopher Reply

        Hi Chris,

        ja, da würde ich eine Vorauswahl treffen – evtl. könnte man ja auch mit einem Fahrradhersteller sprechen.

        Wenn der dir die aktuellen Modelle (nahezu) kostenlos zur Verfügung stellt machst du kostenlose Werbung für die Räder und potentielle Neukunden können die Teile ausgiebig testen (oder so ähnlich). Das müsste man mal mit ein paar netten Folien als Win-Win ausschmücken. Damit kann man bestimmt den ein oder anderen Hersteller als Partner gewinnen, bis jetzt wirkt deren Marketing ja eher angestaubt. Das gleiche gilt meiner Meinung nach auch für viele Bekleidungs- / Zubehöranbieter.

        Um Kunden für den Service zu gewinnen würde ich an kleinere Hotels ohne eigenen Fahrradverleih, AirBnB-Anbieter und jemanden wie HRS herantreten.

        Um etwas Werbung zu machen würde ich Schilder designen die auf den Gepäckträger passen oder in den Rahmen gehängt werden können.

        Das Projekt wird immer interessanter je länger ich drüber nachdenke… ;)

        Beste Grüße

    Hey Chris,

    Welcome to the “AirBnB for Bikes” space! I’m at Spinlister, we do something very similar and we have encountered very similar issues to what you’re facing. We’ve found having a mobile app has helped tremendously with getting bikes on the platform (as people can just take photos in the app) and messaging.

    DM me on twitter if you’d like to chat sometime (@carterdea).

    Hi Chris ,

    I really like your high speed execution model !

    Did you use any tool for visualization of spent time per project or just excel spreadsheet ?

  11. Christoph Glur Reply

    Super coole Idee! Aber viele Städte (wie z.B. auch Zürich bieten schon gratis einen Fahrrad-Verleih. Und die statistische Relevanz der Conversion Rate ist vielleicht auch nicht sooo gross ;-)
