OSET Electric Trials Bikes

The charging block for my Oset occasionally makes odd noises when plugged in, almost like there is something mechanical inside it grinding away. I'm pretty sure it's always done this, but not positive. Normal?

As said in previous post just got little boy brand new 12.5, came in box and just had to attatch handlebars and adjust brakes, the question I have is the chain seems quite tight as the bike doesnt free wheel without some resistance from the chain, its not been used yet as its for xmas its just sat in bedroom, just seems strange when i push it to move it forwards or backwards almost feels bit knotchy. is this normal when new?

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 been researching various lithium (LiPo4) battery solutions for the Oset 16. A cheap alternative I found has been this Eco-Worthy brand which are 12v 10Ah. They are the same size as the stock batteries so I will wire in series to get 36v 10Ah. - On the Eco-Worthy datasheet, what values should I be looking at to ensure the Oset can draw the power required from the batteries? Looking at a total of $189 plus a charger. - Can I use the standard Oset charger designed for lead acid on the Eco-Worthy lithium as it has a BMS installed? This is the data sheet on the Century PS 12100 lead acid battery I'm also considering which is very similar to the stock batte…

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…

Hi all, My lad has the Oset 20.0 and it needs a replacement throttle. Unfortunately I'm unable to locate a new one. There seems to be the earlier version which have two black connector's and the 2014 onwards later versions which appear to have the same connector's as the late 2013 version, although the grips are not the same colour. So can anyone tell me if these later versions will work or if there is another alternative or know of a supplier that stocks the late 2013 version. Many thanks Rob

hi all just tried fitting a lanyard to my grandsons 2007 oset 16 bike. it needs one for youth trials and as it is an old bike it seems it is not a simple matter of fit and go. i have an apico lanyard here and after taking the seat off discovred 2 red wires coming from the switch that have been fitted to it as they are not standard. i have tried using the lanyard using the red wires and when the 2 red wires are joined the motor is fine, when separated it stops, all well and good, when i add in the lanyard the motor will only work when the lanyard magnet is disconected, ie as if the rider has fallen off, the reverse of what should happen? any ideas?…

Wasn't sure where to put this but thought some of you might be interested. Plus I pledged so I'm hoping they reach their $100,000 goal so I can get one of those Free-Riders at a $1,500 discount. https://www.kickstarter.com/projects/1511813482/kuberg-free-rider

Hi, Here is my situation. Ive got a KTM exc 200 and a scorpa sy250 for myself and have until recently enjoyed the odd play in the woods on the scorpa. My start in trials was predominantly to make me a better enduro rider but i dont get enough time to do or be good at either so im fiarly basic levels of both. My son (7 yo) has a 50 cc quad bike that he is growing out of and doesnt have much interest in anymore. I had planned to get him a 50cc moto but then the local coucil put a big sign in the woods on ANY type of motorcycle will be conviscated. This is due to more scrotey kids on mx bikes im sure but i aint taking the risk. So im thinking, kill two birds with one stone…

Does anybody know where you can purchase differant sticker kits such as the ones fitted to bike in link: http://cgi.ebay.co.uk/oset-kids-trials-bike-12-5v-/220706202743?pt=UK_Motorcycles&hash=item33631d6477

Hi all, I recently bought a second hand 2012 24v 16.0 and are struggling to get more than 20 minutes run time, infact the leds in the throttle show "low" after about 5-10 mins. Surely i can expect better than this? So far ive tried: 2 sets of new batteries Checking for excessive drag in the drivetrain (the motor is notchy when spun but i get this is normal?) Checked the balance of the batteries Charged the batteries with a car charger as well as the oset one Any thoughts anyone? Cheers Wayne

Reading on the oset website it says theres becoming a wide variety of aftermarket parts available and alot of bike parts to suit the oset. Has anyone got any websites that do oset aftermarket parts, or know of any parts that would suit the oset from bikes? I wouldnt mind fitting disc brakes and hydrolic levers onto the 12.5, is this at all possible?

As title reads are there any differances between the 2010 and 2011 oset 12.5 model and if so what are they?? Cheers

Hello to all the people! Do you know if the manual for a kill magnetic switch exists? Is for my oset 12.5r 2016 and don't look here this. thanks in advance!! Dani

Just got a new 36v Oset . I've been charging the batteries as directed in the owners manual but the battery life seems poor . The life just drops off the edge of a cliff after about 30 mins of general "section" riding in the local flat woodland . Strictly no wide open throttle MX riding . The battery indicators wouldn't go past the 2nd light as the performance dropped off but the bike was crawling at about 3mph . Even when the bike ground to a halt and stopped it showed 2 lights on the throttle . Our old 24v went 3-2-1 empty . Even our new 12.5 out performed the 36v by dong 2 rides on 1 charge as opposed to the 36v 1ride - 1 charge . Any clues or theories would be help…

Hi All, Anyone had this one? While riding today, bike lost power and intermittently now works. With the batteries fully charged and the throttle showing full power, the rear wheel won't spin. If I lift the rear wheel off the ground and spin it by manually it will start spinning albeit a lot slower than it should be. As soon as the throttle shut off, it won't spin up again unless I spin it manually again. It sounds like motor brushes to me, but can anyone confirm? Cheers all, Wayne.

Hello everyone, I am writing to see if you can help me. As I mentioned in the presentation, we are new to the world of trials and for Adrian I got him an Oset 20 lite, which runs at 36v, the bike came with lead batteries, which barely lasted at all and even less. I have bought a lithium battery for her of 36-42v and 21aH, with a continuous discharge of 160A (according to the manufacturer). The motorcycle now has a spectacular duration, but the problem comes when on some occasion, perhaps when accelerating very suddenly, the motorcycle stops, with the ignition button on, the accelerator lights disappear and the motorcycle stops. To start it again you ju…

Hi all. Has anyone perhaps fitted an bigger ( 11T ) front sprocket to their 24? If so, was there a recognizable difference? Would like to lower the RPM on the motor slightly for the odd occasions when riding some MTB trials. The idea is not to increase speed so much but rather have less stress on the motor when riding some downhill or level sections. Any feedback is appreciated. Thanks

Just picked up a used 20r(2017) when my kids rides towards or away from me i can see that both wheel are no in alignment. We bought it used with no option to return it. Overall the bike is in great condition and really doesn't look abused. If i had to guess i would say the front fork crown is bent.....Is this a know problem and or something i can fix ?? bk

My daughters 20r seems to have developed an annoying intermittent fault, she has complained that it has seemed to very occasionally lose power for an instant and we put this down to a dodgy on/off switch (now renewed). After a very wet and muddy practise last weekend I washed the bike off and dried it but found that the bike's throttle was sticking (it snapped back but the motor kept going?) After checking all the connections and cleaning them and putting dielectric grease on them the bike had no power, it ran as if the battery was flat before coming back to life. This has happened a few times now - Any ideas?
