I have the same idea, and plan on building this year. It looks like you used the Turnigy 80-100. If that is true, Why did you de-rate the motor to half? You might as well have used a smaller, cheaper motor. You could have saved $150US.
Also, If you mount the motor transverse, you gain the opportunity to use multiple motors, thereby beyond 30kW with very little redesign time. Those right-angle gearboxes are expensive and weigh more than an additional motor.
@gabel13 A smaller motor or less gearing wouldn't produce enough torque to start the bike, se earlier comments. If you strive for low cost and high efficiency a hub motor is the best soulution. However, this was more of a technical challenge.
Very interesting. I am planning to convert my bike to an Ebike. I might consider using a 6000W motor (just for saving me from using a gear box, not for the maximum speed). I really like to read about the laws of driving bikes in Sweden. Can you help me by directing me to them on the net, please ?
And is yours loud enough to attract people's attention of a weird thing passing by ?
I should say you'll need some kind of gearing anyway. Please Google: E-cumbent , a very ambitious project by Matt Shumaker, that ended up with a 6kW Plettenberg RC helicopter motor. You have to ask yourself if you want a good and easy built e-bike with a hub-motor, or if you want a technical challenge by using something else.
Concerning Swedish laws the e-bike motor must stop if you stop pedaling the bike, also the effect and speed is limited to 250W and 25 kilometers per hour. In fact it's meaningless to try building a legal one. My bike is not very loud, but you can hear the motor running.

Beställde modellplansmotor med reglage för ca 1500kr från ett företag som Youtube vägrar visa namnet på. Snäckväxel plus batterier gick på ungefär 1600kr. Cykeln fick jag gratis, men uppskattningsvis landade bygget runt 5000kr totalt. På nästa cykel sätter jag dock en navmotor i framhjulet istället och behåller tramporna som back-up.
Som sagt så är startmomentet inte så stort med denna typ av motor. När man väl börjat rulla drar den dock på ganska lagom upp till ca 27km/h. Håller nu på att modifiera växlarna (7 st) så att jag får bättre kraft i starten och ändå får en maxhastighet på drygt 40km/h.
Actually I WILL change the gears, although I'll keep the lowest gear for uphill rides, due to the motors low momentum. (Perhaps it would also be an unnecessary provocation for the the brakes and police with a too high speed?) Also I will change batteries for more range (no pedals on this bike). I'm posting a new video after having done these changes. /B.R. Mats

Good work anyhow.

Nicely done, pretty neat setup

you coulda put a prop on the back and make the motor push you. wouldnt that turn heads?

what Brushless outrunner motor you put (use)

HIMODEL-534508
But remember, although it's possible RC motors are not ideal for bikes, due to low torque at low speeds.

Nice to see someone thinking about safety, with the chain gaurd fitted, nice setup.

looks like expensive gearbox... I considered this, but couldn't afford
dozentrio 1 year ago
Not very expensive really, as I used a standard industrial gearbox, although it took some serious work and thinking to attach the motor to it.

Hur fick du tag på /gjorde du motorn?
Vad kostade det hela?

Det visade sig att maxfarten råkade bli en bit över 50 km/h i stället...
