OSET Electric Trials Bikes

Hi, I'm after a bit of direction with a power issue on my sons 36v oset 16. Turned the key last night after cleaning it Sunday, throttle lights up but no power to motor. Controller clicks as it should when the key is turned. Potentiometer was looking rusty so unplugged the connetor, tried the throttle and the motor kicked but didn't run. Could it be a Potentiometer issue or more? The bike is a 16 with red frame, I've read online that these were released in 2010 and 2010 only but not too sure so don't know which Potentiometer to order! Any help would be much appreciated, Thanks, Lee.

Hi guys, this is my first post so hello from Northern Ireland. I have just bought a 2012 oset 16 for my young cub as all the MX tracks are closed and he needs something to keep him occupied while this lockdown is happening as he's driving me insane lol! Apparently the wee bike has been sitting unused for a year. I brought it home and charged it up for about 6 hours or so. All was good and I was surprised at the power delivery until the boy tried going up a steep hill. It just wouldn't pull him up. Its fine on a flat surface but absolutely useless on hills. My boy is 5 years old and 20kg in weight so surely this wee bike should be able to pull him no problem. …

Has anyone put a seat onto an OSET 16 R? I’ve found some online but they’re close to $200. Wondering if a seat from a 50cc bike would fit. Cheers

Hi there. I've just ordered a set of fork springs to fit in my son's Oset 16 Racing. Apparently they fit in the left hand air fork of the rst forks. They are supposed to soften the ride as the standard forks are a very hard ride even with minimal air in. Was wondering if anyone has done this modification themselves. Do you need to remove any of the existing fork internals on the left side before fitting the springs and what order do the springs go in ? Do they just sit one on top of each other ? I'm more than happy stripping down trials bike forks but oset forks are MTB forks and seem very different.

Hello, I was hoping someone might be able to write me a shopping list for what I need to install one of those controllers to enable smooth power delivery from a standstill. I will hopefully be getting someone else to install the controller as electrics really aren't my bag baby. Looking at my local bike shop, BVM or perhaps just an auto electrician at a push. If someone can oblige in time for the unwrapping on Christmas day that would be great. Regards, Chris.

Remove all Advertisements Hi, I have an Oset 16 spider 2007/2008 year electric trials bike for my nephew.A friend got it new and I got it for my nephews I dug it out the other day to get it fixed up for him as he is now at that age. It has a couple of broken wires and I can't seem to find a wiring diagram for it. I have emailed Oset to try and buy one but have had no reply as yet . I was wondering if anyone has one and could mybe take a couple of pictures of the 2 multi plugs near the battery packs thats where the problems are for reference for me so I can repair it. I have attached a couple of pictures of the area. Any help would be much appreciated I have an h…

Hi guys, thanks for the cool topics and answers that I've been reading for a while now. I disassembled my son's oset 16, gave the frame for powder coating and now I'm having trouble assembling the swing arm... basically the bushings are too small for the holes and I can't remember(or find) if there was anything between the swing arm and the bushings... Any help will be much appreciated!

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.

I've got a 2012 Oset 16 24v that my youngest has now started riding. I'm about to invest in a boost bikes battery to reduce the weight and give him extra riding time but I've got a question about the electrics. Is it possible to upgrade the electrics to those on the newer bikes to get the more flexible speed /power/ throttle response controls and the magnetic cut out?

replaced stock batteries with 2 Milwaukee 12Ah. 3 stock batteries 20lbs 5oz, new batteries 7lbs. battery adapters 3D printed from ebay and XT90 connector. retained with stock cover on velcro's.

In the picture is my daughters 16.0 36v Oset and as you can see I need help. I have upgrated it with a lithium ion battery and a Kelly controller. After installing the Kelly controller the bike ran fine for about two months but then it suddenly stopped working. After some measuring I suspected the controller so I contacted Kelly and got some help from them to search for the fault. I finally got the advice to disconnect the relay and connect power directly to the controller. And with -36v to B- on the controller and +36v to B+ and pin9 on the controller (for powering the controller) the bike works (the key switch doeant work). I also disconnected the wire from the re…

Hi all, I am looking for a little help with my daughters 2007 16. 24v. I recently purchased a new throttle assemble for the bike from the UK as we don't have the dealer network here in New Zealand. The original throttle. The new assembly. The dealer sent me the newer version assembly with a different connector but also the corresponding connector half to replace the one on the bike. After fitting the new part I found that the bike runs fine but the LED display on the throttle is not illuminated. Has anyone come across this before? I am wondering if I missed something or have received a faulty throttle assembly possibly? The dealer stated that this throttle woul…

HI all, Havent had a real CLOSE look at the grips on my daughters bike yet, but just wondered are they easy enough to change? At a glance, the throttle one seems to be all one unit, with the electric gizmo/charging light bit? Would like to change them coz the original seems so big for my daughters hand, and no grip on them. Gonna try to put renthals on there. Any advice greatly appreciated. Thanks

Hi all, got one of these second hand for the kids, im having a bit of a problem with the power, it seems to only give full power for about 30 seconds then gradualy gets slower and slower until it wont move all this in the space of maybe a minite and half, then i turn the key off and back on again and it repeats this. Any ideas on what it could be ?

Hi, after breaking a couple of controllers in the process I’ve now completed a Kelly Controller installation on an OSET 16.0 24V. The problems I had were down to my wiring connections so hopefully this thread will help anyone considering the mod and avoid them making the same mistakes. I have focused on the wiring here as it’s what caught me out. I’ve not added much info on the controller or batteries so ask me questions if needed or look at the other threads that discuss them. First off, even without my controller breakages factored in it’s a costly mod with the new batteries, charger, controller and wiring so I’m not justifying this on a cost basis and will leave tha…

I've bought my son a second hand oset 16.0 36v for Christmas. Took him out today and the chain kept jumping off. I've stripped the bike this afternoon and I believe its happening because the chain needs replacing. The chain has KMC 8F 25HA stamped on it. I also would like to fit new sprockets as they look a bit worn. The front is a 12 tooth and rear 90. Are there any opinions on the heavy duty set that oset sells for £64? Also is the 68tooth rear sprocket in the heavy duty the same diameter as the 90 tooth one it has at moment so gearing will be similar to the original? Thanks for any help / guidance Wayne

I have installed LiPo batteries on an Oset 20.0 48v before with good result. Now its time for my daughters 16.0 but I am not really sure about what batteries to use. I would like to have maybe 12000-16000 mAh and I am thinking about anything from totally 8 cells (29.6v) to 10 cells (37v). Is there anyone here who have done this and what batteries have you used?

Does anybody know of a supplier of tyres for 16 inch rear wheel tyre (upgrade) posibly wider. At the moment it's on 2.7 x 16 . Is 3.0 16 available. Thanks for reading
