Electric bike power

John! Dude! You should be in the Movies!

That was great! Encore Encore.........clap-clap

hehehhe.........Looks like you were having some fun there.

Thats the best clown bike Ive ever seen. I'm still rolling on the floor laughing. Funniest thing Ive seen in a long time. I dont know what I was expecting while I was reading this thead over tha last few weeks, but that was not it!!!!

I say you should take the little wheels off of that bike and strap them on a full size bike frame. Of course it should still be pink.



Nice work man! Looks like a great contraption for hurting yourself.

More Power!!!

That was hilarious! Too bad my bike won't be so much fun...

My next build will keep the rear wheel size (easier to get the right rollout) and have a 20" front. Like a chopper. I will have to mig a frame up, so it will really be a custom motorcycle when I am done.

Thanks for the comments, it is pretty fun to ride :D Maybe a bit dangerous.

JRH is single-handedly redifining how we see transportation.

I can see the future now, middle aged men in business suits riding electric powered little girl bikes to work!

Seriously dude, that was funny, especially the music, and the bright yellow vest. Can't wait to see the "chopper" bike, that should be interesting!

I must say even though your test was not a huge breakthrough in electical science it was a smashing success in humor. A wheelie dumping you off would have been better though. No really even though things did not go exactly as you expected there has to be some amount of humility during any testing phase of operations. I think you are at the very least having fun and learning from the experience. I would love to see a 60 to 75 lb kid drive that thing. I bet it would do much better for them. No pun intended. The thing that is cool is that you have a good number of others here on the site thinking about giving it a go and try their own version. I know I am thinking of trying something like this now. I am just recovering custody of my three young children (9,11,& 12) after 6 years, and the two boys would have a blast working with me on something like this. There are so many options and different ways to go that you could spend years testing and having fun along the way. Still our hearts are truly in the RC arena. Good luck with your future testing and keep feeding us with the comedy shows. That was really funny.

Got version two done. Now I will make a new tranny to double the geardown, and then I will double my voltage on the motor. This should keep wheelspeed the same while halving amp draw assuming I don't goose the throttle more on startup.


I may change the gearbox to include a clutch so that the motor can start up with no load. This will keep me from having to push off on start. So far, I have logged about 20 miles on the new frame. A 6 mile trip costs me a whopping $0.0138 in electricity assuming 10% charger inefficiency. Version three is in the works, I am converting my santa cruz bullet to a pedal/electric motorcycle. Version four is also in the works with a very high power system. Most likely a 90v 200a ESC and matching motor.


This thing is so much fun, I can't believe it took me so long to get it done. I will be selling gearboxes in the future most likely.

[johnrobholmes]

John thats looks AWSOME .

i have a minimoto that i have been debating on converting to BL with a castle 110HV and that 130kv hobbycity motor and run stock lead acid at 36v for now. The gear ratio is already all set up because it is a brushed electric now.

[johnrobholmes]

New motor just came in. Neu 19151y. It shall be perfect I tell you, perfect!

[brushlessboy16]

wow that thing is a beast
