If your afraid that the motor will not fit between the pedals, you can always put a wider bottombracket(sickbikeparts)

Devo i was quoted just over 5kg / 5.1 iirc for the 1000w ...they also told me they couldnt state magnet / stator width for the 1000w due to company policy , winch i know is bull as they state 70mm for 2000w /3000w .. would be good if someone else could ask them and report back.
max torque is mentioned in the description of the middrive system of each motor, and also current and voltage. I believe the suggest peak current will give you the max torque.
The guy i spoke to was giving me lots of misinformation ....my guess was around 8kg.. but do we believe the site info..
Thanks larsb i saw that, solid info .
Well if the qs 2000w has a 70mm magnet width as they state,[vs the 50mm motors ] it should be a great upgrade.
I think it will be fine i am using it at 60volts 250 batamps 500 phase without problem!
That is a great price, depending on battery capacity and power.CSC introduces its first electric motorcycle, the City Slicker, at $1,995
If the frame and suspension were good, it would be well worth it. Heck even slap in a bigger motor and controller. I would want something that is capable of atleast 80kph/50mph. I'd also been on the hunt for a battery charger with 120V(AC) AND 240V(AC) switching capabilities that can rock 1000W+ I'd also want it to be current adjustable. Lots of times you can park it on sidewalk, and if there is an outlet there, be cool to have the charger hidden with just a cable coming out.The City Slicker has two operating modes, Power mode features a top speed of around 45 mph and Eco mode maxes out around 35 mph but gets better range. According to initial claims from Zongshen, riders can expect to travel 37 miles at 37 mph in Power mode and 62 miles at 20 mph in Eco mode. But those numbers might be a bit optimistic, Berk admits.
I have friends driving gulbix 76 with qs205 and at72volts and 200amps , and i can keep up with them with less power and more weight.My senda weights arround 90 kilos and the qulbix arround 55kilos.Yermommy wrote: ↑Sep 27 2018 4:40pmHow would the acceleration compare to a hub motor at identical wheels sizes, power levels, and top speeds? For example, lets say you run 72v 200a through a qs205 5t in a 17 inch wheel and your top speed is 60; how would the acceleration compare to a bike with the qs mid motor 72v 200a in a 17inch wheel geared for a top speed of 60?
Here is a 3Kw charger that is adjustable between 0-120v/0-60v and 25a/50a. Also it can do 110v or 220v.markz wrote: ↑Sep 27 2018 9:19pmThat is a great price, depending on battery capacity and power.CSC introduces its first electric motorcycle, the City Slicker, at $1,995If the frame and suspension were good, it would be well worth it.

Yeah i can imagine that your middrive must have way better ETA - at least when climbing hills or during hard accelertionbionicon wrote: ↑Sep 27 2018 11:46pmI have friends driving gulbix 76 with qs205 and at72volts and 200amps , and i can keep up with them with less power and more weight.My senda weights arround 90 kilos and the qulbix arround 55kilos.Yermommy wrote: ↑Sep 27 2018 4:40pmHow would the acceleration compare to a hub motor at identical wheels sizes, power levels, and top speeds?

oh thats bad,could it be because the controller blew up and go in short?larsb wrote: ↑Oct 05 2018 10:30amIf it's disconnected from the controller and motor's still rotating with a lot of resistance then you've got a short somewhere in the windings.
If you've still got the controller connected then try disconnecting it. If resistance is gone then some fet(s) in the controller is blown.
