hi,
my new project (build some bafang middrivebikes the last years)is a leiba classic veleomobile with a smartpie5 rear motor.
using middrivekits is not possible (too less space) and I did not want to use an geard hubmotor.
so smartpie5 I think is the best sollution for this, I want to use my 48V 17,5 ah battery from my ebike
in austria we have to use a pass-sensor for legal using an e-bike...dont ask me why ?
i ordered my motor with a display, thump-gas but there was no pass-sensor included.
so I ordered this one online with 12 magnets
https://www.amazon.de/SODIAL-Elektrisches-Fahrrad-Assist-Magnete/dp/B07TXTQP6Y/ref=sr_1_30?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&dchild=1&keywords=e-bike+pass+sensor&qid=1602837441&sr=8-30
so can I use this sensor with the sp5 or do I need the gm pass-sensor?
thx and excuse me for my bad english

Hi Hannes and(https://i.imgur.com/evDSMvT.png)to the forum.
Unfortunately it is difficult to say whether that PAS sensor will work with the Smart Pie controller, as they don't mention which signal system it uses. :(
The GM sensors are the Typical PAS type with a single signal wire that sends regular pulses, but only in the forward direction.
Check out the Signal Types for Basic PAS Sensors (https://ebikes.ca/learn/pedal-assist.html) section on the eBikes.CA website for further details.
Some sensors produce a variable analogue voltage output based on the pedal rpm, but those may need to be wired directly into the throttle signal wire to allow them to work. ;)
If you install the wrong type, you may find that it will work when pedalling in either direction, or perhaps not work at all. ::)

hi alan,
thank you for your hint. I think that is not a great problem, because this sensor is very cheap. so I hope is has only basic functions.
if not I order the gm sensor.
thx hannes
