QS 3kw 138 70H + rear pulley 300Eur

Post by minde28383 » Nov 16 2018 1:16pm

QS 3kw 138 70H, nominal mid drive motor with rear pulley.

1 x motor - 280eu (motor 22 tooth 8M HTD pulley factory mounted so it is included in the package)
1 x Rear pulley (to be used with htd8 belt) - 20eu

motor ~7,5kg, pulley ~2,5kg, with box ~11kg, so you can approximate shipping. For exact number drop me your destination, country.

Items location EU. Can ship world wide.

///////////////////////////

Motor unused, new, never was put in any bench or elsewhere. Received from carrier and put it on shelf. Half year passed, project did not develop due lack of human resources. Now human resources available but money spent on other project. Need to collect money from spare parts to move on with other bike. We wish to keep all stuff but can't therefore selling. I'm not expert on motors for sure but I've feeling that we will see this model in more ebikes.
Peaks 10kw, very short peaks 15kw. We are talking about 100+ km/h and fast acceleration from stand still with 1:7 with smaller wheel and 1:4 with bigger wheel.
can be suplied with 120A battery, 450A phase.
Bought from QS directly this spring. Warranty still valid. If requested I can spin it on bench.
Planned to use it in mid drive project but things changed.
If you need more specs I can check in qs web site.

QS rear pulley has 104 or 107 tooth; I can count if interested. Pulley's bearing socket was increased by 1mm from standard hole, because I intended to use slightly bigger outer bearing ring. The pulley also never been installed in a bike.
For both items 320eu + shipping.

added pulley pics.

This motor was bought with Votol. Votol Controller is not on sale, not sure yet about controller. Maybe will keep it, depends on future project. In case you need motor specifically with the controller I can think about that, but at the moment I prefer to keep it as new spare part.
VOTOL EM-150, 24 MOSFET, 200A peak battery current, 470A peak phase current.
