I just put PL350 on my Trek 7000 a couple of months ago. It works really great and I love it. It did take a bit to get used to changed balance as the battery and the motor are in the rear. I mostly use pedal assist in 1 or 2 mode and 3 on hills and in the wind. I almost never use the throtle except for fun. I only ride for fun 30-50km per day and the 37v LiMn battery indicator never runs down below 50%(pretty light use). The kit was on the pricey side $1600 with installation, but the more I ride it the more I like it. If you don't mind parting with some cash, I would strongly recommend the Bionx kit. It comes with 2 year warranty on motor and parts and 1 year on the battery. Just have to keep in mind that the standard Pl355(regular range) is to be used in pedal assist mode as much as possibe. It is not designed for non assist ride and will drain the battery pretty fast. I guess what really works for me is that the assist is proportional and extremely intuitive making you feel like the assist is an extension of my legs muscles. Very well done. And it a Canadian company.

I just purchased a Catrike 700 with a Bionx PL350. oh my. This is also my first post here.

I'm not new to ebike as I made a Three Phase AC Inverter duty Electric Pusher last summer.
The AC motor is rated at 3/4 hp and the AC controller is only rated at 1/2hp. The torque launch is amazing...

but..... this Bionx is unique. My wife tried my 700 tonight and was asking about putting one on her Catrike Pocket.
I never thought she'd ever go for it! We are both 50 years young. This Bionx is no doubt easy to control. I raced
dirt bikes as a kid and love speed. This Bionx makes me pedal for the speed. Also, there is a by-pass throttle. The
ReGen brake is nice on the rear of a Tadpole for sure. I'm thinking of transferring the PL350 to her trike and
switching my 700 to one of the RC motors with esc. I don't know a thing about the RC systems, but lots of info
and help available right here! This forum ROCKS! \\m// my 3 Phase AC pusher trailer project...

Welcome to ES, Tommy L.

I have a Sanyo Eneloop that uses a torque sensor similar to the Bionx to determine how much assist you need. My wife likes the bike so much I built a '78 raleigh rampar roadster using a kit from ebikes.ca which uses a 1/2 twist throttle so we could ride together. I must say, the Sanyo is easier to deal with - you just get on and ride. On the raleigh I have to be careful how I hold the throttle or my hand gets sore from holding it. Also, I find that I kind of obsess over how much power I'm using moment to moment - I like to pedal but also like to use assist on hills or in a head wind. With a torque sensor system this isn't really an issue since the bike decides how much throttle to give.

I do wish there was a torque sensor throttle sold aftermarket for use with ebike kits. Does anyone know how these work in the Bionx or Sanyo bikes? How hard would it be to engineer something like thisl? Are they based on a piezo sensor? There would have to be a lot of support circuitry too though I suppose in addition to the sensor itself.

Ought to be able to somehow push an idler-type wheel against the chain stretching on top to the rear wheel. When force is applied to the pedals, the chain would tighten and move that wheel up slightly. Then base the assist on the amount that sensor wheel deflects. However, it can't be for a through-the- gears assist or the system will move itself to full throttle due to positive feedback.

Thank you for the Welcome!

I'm new to forums.... and I know what hijacking the tread means.... so this is not my intention. (as you read, I have some sort of external battery)

Please educate me, and I will try my best....

I just bought a bike with a Bionx on it. It is a Bionx hub motor, Bionx display, with a separate battery pack, and what looks to be a rectangular box like
a BMS or an External controller. I can't find any stock configurations of this set up. Now I'm worried. Anyone have any input?

I need to know what I have. I'm an owner maintainer and must know.

Thank you!
