Re: Need help converting stock TSDZ2 from 48V to 52V

Hi Linux fan here cos windows sucks :lol: so I'll try and give a little feedback... Why are you using a file from 'eco-bike' website? The latest open source firmware is here methinks: https://github.com/OpenSource-EBike-firmware/TSDZ2-Smart-EBike/releases/tag/v0.20.0-beta.1 The file you use is an as...

Re: New "TSDZ2 Torque Sensor Central Motor"

Hmmm... The more I read the more concerned I become. Now that I have the motor delivered I see what a tiny little motor that really is. Not only compared to one of my DD Crystalyte motor, but also compared to a MAC hubmotor or even a Bafang BBS. I also now see why this is REALLY only a 500W motor, ...

Re: New "TSDZ2 Torque Sensor Central Motor"

I already use my 15S1P 21700 LG 5000mAh for more than 100km, 60% mountain. That's sounds amazing for a 15 cell battery!!! So how many watts is that? How much do you and the bike weigh? I'm looking to buy a 750w motor and a 850C display from pswpower......anybody know if I need to buy any extra cabl...

Re: DIY custom frames, home carbon-fiber method simplified

@paradad or anyone else that's interested
how easy would it be to DIY a simple frame like below, redesigned to have a battery pack under the seat and a motor on the front wheel where the gearhub is?

Re: Motor for fast e-bike

fast e-bike = recumbent - good aerodynamics and low centre of gravity

Re: No Solder, No welding 48v 20Ah. Cheap battery Pack

How much does it weigh??
Weight is everything in cycling to my mind (and to my body lol) :wink:
I want to come to India and buy a motorbike but I can't own one as a foreigner :(
SO maybe I can come over, kit out an electric cycle and try and make it back to Europe :lowbatt:
