Has anyone in the group has tried building a "Bike-in-a-Kit"- a sort of DIY bicycle, which can be entirely assembled and disassembled by the user and can be conveniently carried in a bag ? I face such problem when I've to take my kid for cycling and have to carry his entire bike in my car. Its tedious and cumbersome and I'm not very fond of those bicycle stands/racks that can be put on cars. Suggestions/Answers are welcome.

    Any modern bike can be disassembled / reassembled by a competent person. The folding bike was invented for your use case scenario where you wish to transport a bike inside a car. Look at Brompton bikes as an example of what can be done. – Gordon Copestake Sep 4 '15 at 8:15

Yes they have travel bicycles that can be broken down
enter image description here
They typically use S&S couplers
But compared to the time to break and assemble a rack is less tedious.

You also have folding bicycles
But the don't perform as well a regular bicycle

A break down bicycle is going to have better performance but takes longer for break down and assemble

Break down and folding bicycles are more expensive

On a regular frame you are not going to get much benefit from a full disassemble compared to just removing the wheels. Beyond that lower the seat and maybe spin the bars 90 degrees or remove it. A full disassemble and assemble is hours of work and something I would want to do in a shop with a full set of tools.

  • thank you..its a useful suggestion. I'll try using couplers ! – Ashutosh Akolkar Sep 5 '15 at 7:13
  • Can you please tell me more about the bike in the photograph above ( the one in suitcase) ? What make is it ? – Ashutosh Akolkar Sep 5 '15 at 7:17

Everything has good points and bad points.

Car racks have an moderate expense, initial setup time, and then are very easy to use with virtually whatever bike you purchase (small time investment when needed).

Folding bikes require the purchase of a moderately expensive bike, no initial time investment, but then a time investment EVERYTIME you want to use/transport the bike. They will also generally have less performance and be slightly more fragile than a regular bike. The time investment may be moot if you force your child to do the dissembly/reassembly.

Coupler bikes are similar to folding bikes, but are generally sturdier than a folding bike, have better performance and a higher initial cost.

The drawbacks to couplers and folders also being that you have a limited selection of bikes.

  • Actually, you can often have "couplers" installed on "standard" bikes, as an after-market option. ("Standard" here means round tubes and reasonably conventional construction. Probably not carbon frames.) – Daniel R Hicks Sep 5 '15 at 2:09
  • Given the traffic and road conditions in some places, I'd not want to use the racks, even though as you said, they are less tedious to work with. But appreciate your reply ! – Ashutosh Akolkar Sep 5 '15 at 7:16
  • I am not sure how traffic and road conditions apply. I have used racks to transport downhill bikes to trail heads off-road in a truck. Part of the "road" was a non maintained rock garden. If you buy a quality rack, and learn how to use it, it will hold onto your bike just fine. – Deleted User Sep 5 '15 at 16:32
  • The world record for unfolding a Brompton from its stored configuration is 5.6 seconds. I can unfold mine in about 20 seconds. – RoboKaren Sep 8 '15 at 12:51

You could look online (YouTube) and watch a tutorial on how to disassemble the bike. I'm not sure disassembling the ENTIRE bike would be necessary, though. I would try taking off both of the wheels and then leaning all three pieces against a seat, or if you fold a seat down, the seat and the wall of the car.

I would try this first. Although still a little cumbersome, it would be the quickest and easiest way.
