'Bambike' handcrafted for the 'Tour of Nilgiris'

I decided to associate myself with TFN (Tour of Nilgiris) by sponsoring a bamboo bike to the most sporty person on the 8 day / 900kms cycling rally. I was also invited to flag off the event from Koramangala, Bangalore. (Pictures by Gopu, Aveek & Niya)

 

Media Speak on the Bikes, Trikes

Bamboo Bike - The new Project, May 2009

After my bikes and trikes were successfully running on the roads of Bangalore, a friend approached me with the idea of building a “Bamboo bicycle”. I thought I should give it a try and a few weeks later I felt happy as I finished assembling the bamboo bike in my terrace garden.

The bamboo bike is an environmentally friendly bike as it uses bamboo in place of steel for the main frame of the cycle. Therefore with each such bamboo bike one is cutting down the consumption of steel by 3.5 kgs.

The first prototype was made with raw bamboo with metal sleeves on junctions, as I had not thought of a jig while making the frame (a jig is a metal frame used as a reference for mass production while joining different parts to make an object so that all the pieces are identical.) After testing it further, I realized it had a fish tale effect at higher speeds which had to be overcome.

The second prototype was made using thicker bamboo sections and this time with a jig to hold all members and important junctions like bottom brackets, rear drop out, head tube and seat tube. This time around the parts were glued together without metal sleeves and using hemp fiber.

After I had finished making my first prototype of the Bamboo bike I met Arun Katiyar. Arun is involved with the Ride-A-Cycle Foundation that promotes biking, going green – a small way to give back to the environment. He not only appreciated my work but was very instrumental in encouraging me to develop it further. While I made more prototypes later, he tested them out and gave me the relevant feedback to improvise on the designs.

Later Arun suggested that I build one bike for Tour of Nilgiris (TFN) http://www.tourofnilgiris.com/blog09/. I loved the idea because TFN is one of the challenging mountain biking events, I thought it is a very good idea to put my bamboo bike through the endurance and get further endorsement.

 
 

The tandem out on the roads of Bangalore for the very first time

The Tandem was fun to do because it also allowed both Niyatee and me to take one bike out instead of taking our own individual bike. The maiden ride was from our home in Koramangala to Lal Baug on a bright Sunday morning with a bunch of our biker friends. Needless to say the tandem was a star attraction!   

Both Tandem and Trike have been a great hit with the children in the area where we live as well as when we take them out. The kids just didn't seem to have enough of the tandem. So much so, the parents have asked us to reward the children with a ride if they finish their school work. I have had children tell me that they would rather for-go watching television and ride the Trike or Tandem. It feels good to share a smile with the children and see them so excited.

How about a Tandem Trike? April 2009

After the trike was tried and tested and perfected, I was wondering what next. I was fiddling with the idea of a trike with shock absorbers when I chanced upon a tandem trike. And I said why not.

The tandem took roughly a month to make from the conceptualization till the final execution. There were a few learning’s from the earlier model of trike which made the design of the tandem more refined.

• The weight of the trike was 29 kgs, while the tandem was 30 kgs in all. I realized the earlier trike design was over-specified.
• Ergonomically the tandem seating is more comfortable
• The trike seat was welded with the frame. While in the tandem the seats are removable, which makes it easy to dismantle and transport.
• Brake system was improvised with the introduction of disc brakes.
• The axel of the front wheel in the tandem was modified as it would have to carry the weight of two people. Instead of conventional hubs I decided to go with bearings. 
  

Trike on the Bangalore roads

Once the trike was ready i was eager to take it out for a road test. The first ride on the busy lanes of Koramangala, Bangalore was an exhilarating experience. Not only did i thoroughly enjoy the ride of my hand made trike, it attracted lots of attention on the roads. It gave me instant "celebrity status". People in other vehicles including BMTC buses slowed down to look at me - give me way, kids jumped and shouted out to me in excitement, some even ran along with me! Some curious folks stopped me and asked questions about it. Most of them couldn't believe me when i told them i made it myself. Some even thought I was disabled and this one man actually asked me if it was specially designed for me!

Check out this small video of my first road test of the trike in bangalore. It was an easy ride!
