Another oddball motor from Bafang isn't even on their webpage but is something that fits an interest of ours is this geared motor designed for a wheelbarrow.
What is the rim size on this wheelbarrow motor? Any more info somewhere?

Re: Low KV 1000W BLDC

Like Lars already asked: why not a geared motor? My DPV (cheap Chinese Seadoo knock off) uses a geared motor. Look at Cyclone motors: http://www.cyclone-tw.com/motor.html The 650-1680W geared version might work for you?

Re: Downhill bikes as donors for mid drives?

Yes there are numerous builds on E-S using downhill bikes as donors. They are ideal as they are full suspension and have a "relaxter" head angle making them ride better (less nervous) at higher speeds.
The new CYC X1-Pro motor kits seem ideal for a conversion: https://www.cycmotor.com/x1-pro

Re: Gas electric hybrid questions.

If it is "just to have a project" then go ahead building this hybrid bike. If you need it as transport/commuter then just buy a bigger cc petrol bike. Because the extra complexity to make it all work (and keep working) together is not worth it financially or time wise. If you just want the "electric...

Re: hub motor options for tires with stub axles?

Why not use a 3kW Cyclone motor on the rear axle/chain drive? Only one motor and controller needed then.
What weight and speed are you going to go with?
If the weight and speed needed aren't too high and the hills not too steep you can even use a 750W tricycle kit.

Why don't you tell or show(sketch) what you want to build? Why not electric only? Why the ICE? What riding do you want to do with it? I.e. distance, speed, (steep) hills?

Re: Gas electric hybrid questions.

Not sure what you are building exactly? Yes the electric motor will have drag/resistance when rotated without powering it. This can be solved by feeding it enough voltage at very low current to keep it spinning along with the ICE (Internal Combustion Engine). When you use the electric motor as a gen...

For that price i hope you're looking for 20kW peak power? Cyclone has a 18kW motor and controller offering that is $599.- + $299.- = $898.- excl. shipping and cuctoms.: http://www.cyclone-tw.com/motor.html Maybe almost the same motor from Eastgem at 15kW peak: http://www.eastgem.net/d9000.html But I...

Very nice result :thumb: But you don't want a belt as in the original ICE scooter CVT kind. That would cost a lot(!) of efficiency resulting in a lower range and top speed. If you want a belt then get a HTD belt and pulleys to replace the chain and sprockets that you built in the casing. I still thi...

Re: Denzel 72v 4-spd Gearbox Build DB17

This motor with gearbox is mostly suited for ATV/quad/cargo 3 or 4 wheelers IMO. Not for narrow 2 wheelers/bikes.
The fact that you only need a simpler/cheaper battery pack to be able to haul heavy cargo and/or tackle steep hills by selecting a lower gear is the selling point of this combination.

Re: Good resource for those in need of help

Good result!
Just a shame that a knowledgeable guy like him seems to build a battery without cell holders but instead by glueing cells together and not using extra protection rings on the positive terminals. That doesn't appear very professional.
