Hi guys
I'm new in this forum and in the E-Bike world but have years of bike frame projecting-construction experience and near me artistics welders and designer.
Before I start explain the topic-subject let me say sorry for my bad engl. and thanks to all who post here, I read a lot of topics before deciding to write and was an exciting-learning experience.
The project is to use a well tested strong&light DH-Freeride handmade frame to make an Electric fun-climbing-DH-bike with like 3000Kw power but maintaining the light characteristics of the frame (around 16.5Kg race-ready / 3.5Kg frame+rear shock).
The goal is to stay inside 30Kg (mean 13.5Kg for all the electric stuff) or better near 25 (mean 8.5Kg), so I need the best for materials/reliability, price is important but secondary, obviously the max speed is not important but the climbing ability and the acceleration.
The idea is to redesign/change some of the ergal CNC lattice plates of the downtube and to enlarge some of the holes like the pivot and the bottom bracket to accomodate a central motor (maybe RC?) with a simple as possible transmission and the battery without compromising the geometry of the bike.
I'm also searching for info about brake recharging
Wath I ask to the forum is to help me decide:
- the motor (type - brand - model), advantages and disadvantages
- the simpliest way to efficiently transmit the motor power and reduce rpm
- the best battery packs avalaible - controllers and electronics stuff, advantages and disadvantages
the two possible frame base are:
