For the past month I've been working on building an electric trials bike with the idea of having something which is trail and trials ridable as well as still being able to be peddled, things are coming together and the bike is impressive although I still have some work to do in getting the low speed power delivery into a more controllable state, as it sits now the intitial torque is abrupt and at times scary, I am going to have to buy a different throttle, the one I have is just over 1/8 turn from full off to full on. not having a clutch or engine sound is also going to take a different style of riding, but its a blast to trail ride. So, I started with a Jackflash. Switched the rear wheel to a 24" downhill wheel with a 24x3.00 tire, installed a boxxer fork and have it set up as a 3 speed using a 9 speed cassette and X-9 derailiur with a X-9 3 speed shifter, this setup shifts 2 cogs at once and works perfectly, I also set up the speed controll to have 2 power settings by flipping a switch near the throttle, I am still experimenting with different programming for the power settings to help calm down the torque. I fabricated the battery compartment from aluminum and the bodywork and fenders from glass and carbonfiber along with a hell of alot of work and fabrication for the drivetrain. The bodywork was time consumming but in the end I achieved the look as was after which is to have the bike look clean and uncluttered, still resemble a bicycle but have a very mototrials flavor, the seat is teloscopic and can be raised to a comfortable height to peddle if needed. I dubbed the bike " Pedatrial AGB" ( Anti Gravity bike) since downhill bikes are known as Gravity bikes I thought this was appropriate. I got out for a ride yesterday and took some video, the video is raw, kinda crappy and uncut and with the fisheye lens it doesnt really show just how steep some of the terrain is, I can say that I cant make alot of this on my mountain bike and its steep enough to be difficult to hike a bike up, the pedatrial just ate it up and I now know I can gear it up since I never used low gear.at one point around 8.30 in the vid you can see where the twitchy throttle caught me off guard.
