Looks like we are seeing a new class of vehicle emerging.. a crossover .. a "Pedalless Bicycle" or Ultralight electric motorcycle using mostly bicycle components.
Now BZH & Skeetab have got their BHT powered bikes running it looks like that motor will become the (or at least one of the) standard motor(s) for this type of bike.
I haven't ridden an OSET 20, but my grandson recently got an OSET 16 to move up to when he outgrows the electric bike I built him for Christmas. I like the mechanical simplicity of the single reduction, single speed, motor on swingarm system, and the performance of the OSETs in junior competition trials validates the design for that purpose at least.
I will be ordering a BHT motor and Kelly controller in the next few days for my pedalless build.
Yeah, far from a bicycle for sure. Superlight electric moto is more like it. Once you take the pedals away it really doesn't match the definition at all. Stick a moto seat on there and it doesn't even look like a bicycle anymore. Truth is, I find bicycle seats unfortable (especially on impact landings) and I really don't see a point in having pedals on a bike with this kind of power except for the legal reasons. Pedals seem to add a layer of complexity along with weight and it seems that most just use them to get started or when climbing big hills. I don't intend to do massive hill climbs and I think this motor should have enough grunt to make starting a non issue. I don't really care about the legal aspect. I am more likely to register it as a moped for street use than try to convince people that it's still a bike. Where I live, it really doesn't matter all that much. That said, maybe I picked the wrong subforum, but similar builds with the same motor are here so I figured what the hell!? hahazener wrote:

For me it looks like a light wight motorcross with steering parts from a DH bicycle and 'maybe' a DH bicycle rear shock.
The new 25R or little better but more expensive VTC5 would be nice but they get pretty hot and sag much @ there rated max ampere. If you calculate with half of that rating for pulse discharge you are on the safe side.
If u take 200 from them than 8KW output power is safe.
Yeah it is. EP-OSET-HB32H Alloy, anodized red, 12G (spoke dia.) x 32H(spoke QTY) x 3/8"(axle) x 139mm(drop out width) x 180mm(total axle length)bzhwindtalker wrote:Is that the OSET 20" hub? could you share some specs? thanks!
