So Im redoing this thread, too messy in last attempt....
Ive lately starting to get interested in single trail riding, and have 2 bikes equipped with tsdz2 motors. One fatbike for the easy rides, and one full suspension Liteville for going up the steep stuff, and trying to get back down without breaking stuff. I mostly use the FS bike in the summer. I like pedaling (well, sort of. I need the exercise, and I get lazy if I have a throttle), so I enjoy the torque sensored lightweight tsdz2. That is, until they started breaking. The spindle broke on the fatbike, and the tsdz2 on the FS bike let out the magic snoke at 982km. There's been some other small bugs with the tsdz2's also, enough for me that I want to move on to something else. Ive learned so much from this page, so I want to make a build thread, in case someone else is looking for something like this.
The easy solution is to buy a commercial emtb, PaulID's excellent kit, or wait and see how the lightest.bike kit will be, but knowing myself, I will never stop customize the bike, so Id rather put something together myself.
Build goals:
- Mid drive
- lightweight (sub 20kg on the FS bike)
- torque sensored
- 6-700w peak power
First problem is finding a solution for the torque sensor. The power from the motor must not affect the sensor, and I need a freewheel. Luckily, the CYC X1 kit has this, and parts are readily available in their webshop. So I got one for the FS bike.
I will use a cycle analyst to process the torque sensor signals and display information.
