Does anyone have experience with the EarthX battery pac for the Oset 16" 36V? I'm no electrician and have none experience putting a Rc lithium battery pac together for my son's Oset?

Hello, I have recently got an oset 16 for my lad and it struggles with grip on the rear tyre. I was just wondering what is the biggest tyre anyone has managed to fit to it? I am currently looking at a 3.5 inch wide tyre but I am woried it will catch on the chain. Apologies if this subject has already been covered but I searched through the forum and couldnt find anything.

Is there anybody who sells the lithium batteries made up already for the 36v oset or can tell me what I would need to make them and what charger I would need.

I purchased the 16.5 for my grandson a few months ago and just rode it for the 1st time last week. I seemed fine an we rode around the back yard until the batteries started to weaken. I put it on the charger and when I got it out tonight it there was no power. It would barely carry my 50 lb. grandson around the yard. I put it back on the charger and when the light turned ""green" I tried again, same results. I get my voltmeter and 1 battery checked 12.98 volts and the other checked 13.12. I lost all the paper work during a recent move so I'm in the dark on further troubleshooting. So - does anyone have a scanned copy of the original owners manual and has anyone…

I wasn't sure if this has been covered or not. At a local trial here in the Pacific Northwest of the States, a man pitted next to me with two very interesting bikes, Naturally, I forgot to bring a camera that day, and further forgot my new "smart" phone is also a camera. I wish I'd taken some video or photographs of these bikes that day...... An interesting thing, to me, was that these motorcycles were both hand built. Things like the suspension & brakes were sourced, but the frame, swingarm, plastics, & such were built by the man parked next to me in the pits. He's an engineer/welder/fabricator/designer, and did what I considered a very good job at building h…

Hi Has anyone else had this problem with their Oset? My Son was riding in a trial when the bike stopped, Red indicator light showed 3 Reds,Dropping to 1 when any throttle was applied.Further investigation revealed that the chain had come off, I refitted the chain to the rear sprocket but noticed that their was approx 25 mm of play in the chain at mid position. I adjusted out the play to 1-2 mm as per manual,This was a very big adjustment on the rear wheel, I am used to making slight adjustment that are required to eliminate the chain touching the plastic chain guard. Upon turning the throttle the Red light dropped to 1 with only a slight Forward movement of the Bike.…

I thought I'd share a recent near miss I had with some lipo batteries whilst attempting to convert our little lads 12.5 from lead to lipo....... After running a 36v (pairs of 5s batteries in series) 16" bike on lipo for a while with no problems I decided to get some for the young un's 12.5. Went for some of these http://www.hobbyking.com/hobbyking/store/__56843__Multistar_High_Capacity_6S_8000mAh_Multi_Rotor_Lipo_Pack.html which, after careful measuring, seemed like they would fit nicely. Once they arrived I taped them together, wrapped them in some 8mm foam and duct taped them up. Trying them in the bikes battery tray they were a good fit, just dropping in under the…

I recently had yet another set of off-the-shelf batteries blow up (overheat and swell, not explode). This time was a set of three 10.5ah SLA batteries, that I believe are PowerSonic brand. But this is the 3rd set in about 3 years: First a set of 8ah's on our 12.5 model (w/ a stock Oset charger). Then a set of 10.5's on a 36v model (I then replaced the Oset charger with an ebay 36v charger) Then this set of 10.5s on one of our two 36v models. To the best of my knowledge, I haven't left these things on charge more than overnight, or 24 hours. I tested both of the two chargers we have (1 Oset and the one I bought on ebay) and both are putting out about 41v. There…

Morning all. Went to get my boys oset 20.0 lite out of the shed yesterday, fully charged, swithched on on the handle bar, 3 lights showing on the battery gauge, and nothing. When I say nothing, you hear the relay make the click noise but when you touch the throttle there is a slight response where the wheel turns a fraction then it cuts out. Repeat process and it does it again but nothing more. It was fine when we put it away after a dry ride. Any thoughts???

Newbie here, just joined forum. Just purchased brand new OSET 12.5 for my little 4yr old boy for christmas, he did have PW50 last year with stabilisers but had so many crashes due to the stabiolisers he ended up too scared to ride it so ended up selling it. He had a quick try out on oset 12.5 and loved it so used the money from the pw and some extra for xmas and purchased a new one. He has all the clothing and boots from when he had pw but would like to purchase a childs trials helmet as the one he has is an mx full face helmet, does anyone in south west area sell them as i would rather him try it on than guess and buy one from the internet. Many thanks...

Hi, I have just purchased an oset bikes (small one), but i am having trouble trying to keep the bikes at very low speed, is this normal? i set the speed with the throttle right open and adjust t down to slow walking speed, my riders are still trying to get to grips with the brakes so don`t want it any faster, when it is turn off by the key then back on again after a minute or so, the speed increases (fast walking pace), also the speed adjust seem very very sensative, i`m worried that the speed could increase whilst the bike is in use, and as this little machine is so powerful it`s quite scary to think it could take off with my little one on board, any tips or advice??

Hi folks, Sounds like the motor bearings have failed on the wee boy's Oset. Anyone out there replaced them as advice would be welcome. Thanks in advance.

I bought a used Oset at the weekend for my son. Its a 12.5 model. I put it on charge and let him have a bit of a go out the front of our house as its very quiet. After a few minutes the bike would barely pull him up a small hill in the road. I put it on charge when we got in and it was on for about 8 hours but the red LED on the charger never turned green to say it was fully charged. I took it off charge and lifted the back wheel whilst I turned the throttle. I held it for about 30 seconds and you could hear the wheel gradually turning slower. The following day I left it on charge over night and still no green light. Do you recon the battery needs replacing? When I lifte…

Hi new here looking for a bit of advice on a bike for the kids, one is four and one is six they are 41" and 44" tall and both ride pedal bikes, and both started on balance bikes. They currently ride islabikes pedal bikes the lad on the one that has a seat height the same as the 12.5 oset and the girl the bigger one with seat height same as the seat height as the 16 oset He Has his seat about an inch or so higher than stock and is confident standing and flying round and can get on his sisters bike balanced on one foot and would probably ride it given half a chance His sister rides the larger bike but not with as much confidence as him she was more confident on the smal…

Hi, Has anyone tried the above on a Mecatecno? Mecatecno only do the standard teeny-tiny chain which Adam has just snapped. The logical choice seems the heavy duty Oset one but looking to see if 1: the sprocket fits and 2: the chain is the right length for a. Mecatecno. Trials UK were very helpful but couldn't guarantee either fit. Or correct chain length. Anyone know anything?

We purchased a second hand oset 12.5 for my 3 year old son. It has subsequently developed an issue where is cuts out and we have to turn it off and on to reset the motor when he accelerates hard from a stand still. The bike will not cut out if we hold the back wheel up and accelerate hard so it seems to be a load issue. If we help him accelerate at half throttle the bike runs fine and there is no issue. We have looked at all the wiring and replaced all the fuses on the bike that we can see but the issue persists. Has anyone encountered this issue?

Hi. I would like to change the original throttle from an Oset 20R 2017 to a Domino el- throttle. I do have the wiring chart for the Domino but not for the Oset original throttle. Does anyone have the wiring chart on the Oset original throttle they can share? The wiring have different colours, so I would need which colour goes where from the Domino to the Oset Throttle. Anyone done this modification and have any experience? Thanks

Hello proud parents. How do you teach your kid how to wheelie on an Oset? My son really wants to do them, and he practices in the driveway going over a log for countless hours, but I can't seem to explain to him the proper way to use his body motion and coordination with the throttle. I'm not talking about doing any kind of long distance wheelies, he is simply struggling with being able to lift the front on demand. Anybody willing to share their teaching aides or tricks?
