Check your throttle knob. What voltage you have min-max? On one of my bike throttle and cadence sensor was fried during re-flashing. So I just replaced throttle and motor started working, but pedal assist still off, I waiting for spare parts.

According your sketch you will newer have touching wheel to battery case if you place it under bottom bar. If you don't use bike for agressive downhill it is simpliest and cheapest solution. BTW, I recomment fix battery case to frame by worm drive clamps.

Be careful, torque is very high and could beng/break this arm. I used aluminium profile 1mm thick and once I found it was broken and motor turned around BB.

In all cases same hall sensor was fried? if yes - seems there is some overload in circuit. Till you waiting for new controller I can recommend add small resistor ~50-100kOhm after third leg of hall sensor. May be it solve problem. Other way - check voltage between first nd second legs, must be...

Yes, I know, but I want to keep the battery removable, because I have two e-bikes that I often load/unload in the trunk of my car, and with the battery they are too heavy.

My build: Case 13S5P - no way to install inside of triangle. Since last December no problem, but I increased springforce to max value.

99% sure it is SS41f If you will replace - do it for all 3 sensors. https://www.aliexpress.com/item/33020628645.html or similar

Hello all. I posted my question in parallel topic but without answer, so I try to ask here. I have new motor 48V 750W built in December 2019, I ran about 50 km (it was several trips across snow forest) and once I found my motor not working neither from pedals, neither from throttle. First, I...

I ordered separate PAS sensor from aliexpress for 1 USD and dual hall sensor VF526DT, will try to replace broken hall element in TSDZ2 sensor. If I right, in our controller there is two hall elements integrated in one unit - one for direction, other for cadence. So we have 4 wire: ground, +5V...

Hello Casainho, thank you for fast reply. May be you right, I only had little hope it is unknown ug or configuration mistake. Could you give me info what cadence sensor is? May be I can repair or replace it instead of buying new controller? Do you know what each wire mean? If it hall sensor, is...

Hello all, I built two TSDZ2 e-bykes, first with 850C display, second one - with OSF adapded for VLCD5. I ride first byke since December last year with firmware v. 0.6.7, everything was Ok. Now it is not assisting and I can't understand why. I updated firmware to latest one 1.0.0 alfa4, motor...
