Lucky kid! Bike has some nice upgrades and live on kickstarter. https://www.kickstarter.com/projects/raffebikes/electric-motocross-mini-dirt-bike-e-bike-motorcycl?ref=nav_search

Agree, and that thing sure does looks shweet! The word should also get around as to who actually won it as this is such a tightly knitted community, mx/trials.

Turned out very nice. Great job dad.

Any updates?

Richard, I have a late model 12.5'', and the OSET controller didn't run on 36v. Test yours with an extra battery.

Nice. Looks like the 16'' pegs.

Very nice work. So is the entire swing arm all aluminum now?

Didn't realize you were in the UK. Tell you what. If you would like, send me a p.m. if you are in need of one and ill send it to you for free, just pay the shipping. Paypal me the shipping and its yours. Get your girl riding safe.

Hi Steve, Welcome to the forum. I also have a 36v, the newer version with the latest electronics and recently just for giggles I put 24v to the 36v controller, and it didn't fire up for me. Seems like they might have the LVC gwhy is talking about. Well the real reason I tried it was because my son races his Oset in motocross and I wanted to see if I could run it on 24v's incase one of his batteries went south at the races. I converted my sons 12.5'' to 36v's. Ended up swapping in all my electronics from the 16'' 36v, so that left my 16'' without any electronics. Now I have a complete 24v OSET system from the 12.5'' stored in a zip lock bag. I would love to trade you my 24v controller and throttle for your 36v controller and throttle. We probably would not spend more then $4 each in shipping. The 24v will go down to a crawl. Let me know if that interest you. I can ship mine out as fast as tomorrow . We can pm each other if interested and we can exchange contact info. If you need the 36v back later we can swap back no problem.

Did you do a before and after weight difference? Also before and after the frame mod?

So what would you do for a motor to reduce the weight while keeping the power?

Yes I meant the diameter of the tire. You are correct OSET does measure the diameter of the tire, I think the bicycle industry does that in general. Congrats on the bikes and the kids riding. These E bikes def get them going early.

Very nice. Are those 16'' wheels? The bike some get pretty long run time with the 14ah. What size motor and what is the controllers output?

Excellent! What I love about these OSETS is that they are a GREAT platform to tweak to make make them fit ones needs. Are you gearing him towards MX? My son got his 12.5 at 3yrs 3months. Before that he was on a balance bike at about 2.5 then the first moto was a Razor MX350, then moved his onto the OSET. He is now 4yrs 3months at 39lbs. He out grew the 24v power so I fitted the 12.5 with the electronics from another 36v 16'' I bought to play with him. He rides it at full power, with the 500w motor. Its an impressive little machine. Last time I checked he was exactly 3.3ft, maybe about 3 weeks ago. He is now at the tipping point of being to big for his 12.5, but the 16'' still to big. We ride strictly MX, and is currently competing. I am making a hybrid between the 12.5 and 16''. GWHY has been extremely helpful in making this right. ANYWAYS sorry for this long story but wanted to share another little guys story that might help in your project. I'm all about having a bike for the little ones that fit THEIR scale. Makes it FUN for them and best of all it builds their confidence. When he was just 3.5 we were at a local track and rode a friends pw50, he got around the track, but you could immediately tell the difference in his confidence level. On the OSET he could literally go anywhere. He was maybe 33lbs then... on a 85lbs pw50! I would not like to ride a 550pnd MX bike . Kudos on the frame mod. Lighter is better!

Perfect thank you.

10x12.5 rim

Thanks to gwhy's advise I will also be lacing a bigger size rim, but on the 12.5. My kid is between being to big for the 12.5 and still to small for the 16''. I bought some used front and rear KTM50 1012.5'' rims and will be lacing those with the OSET 16'' hubs onto the 12.5''. I have not received the rims yet, but I am sure the spoke diameter is bigger then the OSETS, so dremeling out the OSET hub holes might be pretty easy.

Just tried this, and also nothing. 24v yes, 36v no wheel spin but all else does turn on. I guess the only conclustion is that the newer 36v controllers do have a safe guard.

Well I bypassed the relay and same thing. With no relay, 24v works fine, as soon as I add the third battery no more wheel spin. The throttle lights up with 24-36v, but just no wheel spin on 36v. Even ran down it batteries while on 24v to bring the volts down. With both 24v-36v I can hear a click inside the controller when first connected. No idea.

betarambo Yes the relay does activate. Even the throttle lights turn on as if everything is working, but the twist of the throttle is dead, as if the limiter was all the way down.

Yeah not sure. Maybe the new controllers are set up differently? I''ll see about eliminatinig the relay. For now, the 12.5 has the full 36v setup, throttle and controller with the three 10amp batteries from the 16. It HALLS! Still need to get the lipos though. Has anyone ever tried 48v on the 36v controller?

Yes the rear black wire is going to the back negative. Yes when switching from 24v to 36v the 24v will keep working so nothing popped. I just simply disconnect that back batteries positive from the top battery and loop the front batteries negative to the rear batteries positive. I also turned the potensiometer (sp) back and forth. I will try the volt meter. I need to go buy one. Assuming it drops voltage what would that mean? The batteries are pretty much brand new and work great on the 36v, and are topped off. Thanks

Hello, Hoping someone can shed some light here. I installed the three batterys from the 36v 16'' into the 12.5'' to do a free "test" 36v run on the 12.5''. The controlls turn on, but no wheel spin. They are the stock 12v 10ah batterys from our 16''. I connected them I believe correctly just as the 16'' batteries are connected. I looped one of them out for 24v and works perfectly, as soon as I loop the third battery in it has no wheel spin. Here is a picture: Any ideas? Thank you

Well I guess you can't practice standing down
