OSET Electric Trials Bikes

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 tried the lighter rear spring available on eBay for the 20R ? The stock one seems a bit stiff just wondering if anyone has some feedback thanks

Hi all, I just picked up a used 2015 20.0 for my son to ride while we wait for the 20" TRS to show up stateside (indefinite covid delays). I'm planning to do a custom lithium ion pack for it as we did for his smaller, Oset. Thinking ahead, it's likely that we'll sell this 20.0 once the TRS shows up, and there's a good chance I will snag a 24" for myself to putter around the yard. So given this, it'd be awesome if I could build his 20.0 pack such that it would also work in a 24R in the future. Trouble is, I've never seen a 24R up close and do not know what the battery space is shaped like. If anyone could post pictures and measurements of a 24R battery pack that would…

Hello All, My grandson is interested in motorcycles and turning three. His mom seems open to him riding trials (versus mx, etc). I am imagining that kids outgrow their Osets regularly so they come up reasonably often. Does anyone know of one available in the NE US? Thanks, Ward

I'm not willing to risk with LiPo and don't really want to geek out on stuff or have some super fancy setup. Any problem with just buying 3 of these and running in a 3s setup and then either charging as 3s or having a separate connector to charge them individually? I might go for 20AH version too, spendy but I like the idea of having tons of range. https://www.amazon.com/ExpertPower-Lithium-Rechargeable-2500-7000-lifetime/dp/B07X3Y3LS5?th=1 They look like they got a good BMS in them so I'm thinking if I charge them as-is (3s) with enough voltage they'll be fine, no?

I just got a used 20, the batteries are pretty much shot but rode it 3 times for 10 ish mins. The foot peg mounts are bending and the bolts are coming loose. Im a little over the weight limit at 240. wondering if I shouldn't just weld some on or is there another way? I have a CNC in my garage so I may try making some brackets that use all 4 mounting holes before i perm mod this thing. Also wondering what the recommended AGM batteries are. i cant spend 1k on a battery upgrade right now since I was lucky enough to find 3 used osets in the last month. I am also thinking about making a rear brake pedal mod getting crafty. Man when I pull this thing off the charger the first 2…

Has anyone put center mounted training wheels on the Oset 12.5 (not rear axel mounted)? Like www.wheels4tots.com?

My son is eight and is the final year of the D Class. He is a reasonably good little rider, riding the hard route in OSET Cup events and in Adult events the Sportsman route. Due to his physical size we haven't moved onto a Beta 80 like the majority of his friends. OSET bikes have been fantastic for us, he has had the 12.5R, the 16R and now the 20R but now his friends are on petrol hikes and he is getting flustrated with the bike. He finds it hard to find traction despite me running about 2 to 6psi, depending on the conditions and venue. We run two rim locks on the rear with a Cheng Shin tyre (I am not aware of any other tyre option, is there?). But I think the m…

Hi, I've installed a kelly controller onto my sons Oset 20 which is running a genuine oset lithium battery pack. I've followed the wiring diagram from kelly and also from an article by Mxoset on here. The controller powers on and I can configure it with the laptop but I'm not managing to get it working the motor. Any help/advice appreciated.

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

Hi All, Looking for some simple help and guidance on a Lipo Conversion. My son is very small, so I'm looking to save weight and increase range! Does anybody have a list of exactly what bits I'll need to oder from Hobbyking, to do the conversion? Understand that I'll need a balance charger and monitor/alarm system on the battery pack itself. But, what will we need in terms of connectors and the batteries themselves? Many thanks in advance! Scott

Anything specific to look at when buying a used 2017 Oset 12.5?

Tonight I noticed the relay has been clicking away on the bike while it was unattended. Upon closer inspection the battery switch was in the on position, the ignition key was in the off position, the kill switch lanyard was in position, and the lights on the throttle housing were flashing erratically. Twisting the throttle resulted in the rear wheel turning, even though the ignition switch was off. The only way to switch the power off is to either put the switch on the battery in the off position or remove the the kill switch lanyard. Can anyone help me with this odd issue please? Thanks in advance, Tony

Hi, has anyone found a suitable heat sink to use for the 24 r motor to help keep a little cooler?

Hello! Just got a 2012/ 2013 20.0. Previous owner said the batteries are new. When I charge the bike the fan continually cycles up and down i.e. speeds then slows. Anyone know what this might mean? Seems to happen after the bike has been on the charger for 20 mins or so. I'm aware not to charege for more than 5 hours. Thank you!

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 first post so hellooo.... I would like to get into the trials scene as I have recently bought my daughter a torrot and going anywhere with her on my ktm is a big no no these days so I am looking at getting the oset 24 but i am a little worried that being 6ft 2 it will be a bit small, is there anyone else this tall who has one? Are they ok and what mods can be done to make it ok for us lanky folk? I am in the weight limit so that is not a problem and I will also be getting a better battery for it so I'm just concerned about them being too small. Cheers ?

hi just bought an oset today and i was wandering how to date it, it is an oset 20.0r but i am unsure on the age of the bike. any help would be great

I thought I'd start a thread to show some of the mods we have done to our Oset 20. Maybe other people can do the same and share any little tips to make it even better. The standard brakes were not to his liking and the pads wore through in a very short space of time the day before Christmas! Faced with the possibility of not riding the bike until the new year (because we couldn't get new brake pads sent) we bit the bullet and stuck some Shimano XT's on there. Awesome brakes! Also did some Renthal grips and bar ends while were at it. The motor was getting covered in muck and so we used an old heavy duty 18" inner tube cut to the right size and shape to make a mud guard…
