OSET Electric Trials Bikes

I cant find the potentiometer. I've pulled the covers, and the place where the POT should be is empty. Assembly fault, or are they an optional extra now?

My sons oset just stopped moving all of a sudden. All lights are on the handlebars, but it just isn't moving. I've checked the wires and they all seem to be connected properly.. do i suspect the worst in that the motor is broken or could it be something simple?

Hi, My boy is getting a 20.0 from santa..... can he enter local youth trials on this ? .. what are the rules ?, advice appreciated. Thanks

The Stratford-Upon-Avon MCC are running a club trial at Hancocks Wood near Broadway on Sunday 17th October with a seperate conducted route specifically aimed at riders with class E licences on Oset electric trials bikes. The normal club trial will include three routes plus the additional two routes for small wheel machines at the top of the wood near to the car park area. The Easy conducted route will be suitable for youngsters aged 4 to 6 years old with the Hard conducted route suitable for more experienced riders on machines such as TY80's. Trophies will be presented to the top three on each route at the end of the trial. The event begins at 10.30 am and is signposte…

Anyone know where I can get a workshop manual or exploded views for a 12.5?

Hi All I have a new 16 36V Oset and im not sure about the batteries... On full charge they last for about 40 minutes to an hour then the light drops from 3 to 2 and the power reduces considerably. My son rode it yesterday at trials practise and thats when we noticed the power drop after 40 minutes although he was riding in the wet mud. The same happened today but he was running mainly on tarmac hence the 60 minutes before drop out. I charged it up fully overnight last night and it seems to have lasted a bit longer, we will have another go tomorrow. Is the sudden drop in power normal...? Nick

I have just picked up a used Oset and notice the motor says 900w which appears is the same as the 20 lite. Are these out of the factory like this or could it be a upgrade? Oset spec suggests 800w is normal. Cheers

My 8 year-old son enjoys trials events on his 36v 20" Oset but also has the desire to "go fast". So, is like to get more speed out of his bike. I know that larger rear sprockets are available but have not found smaller sprockets. Also looking for 20" street tires. Any advice or leads are appreciated.

Wondering if anyone can help me. My son has had a oset 20r for a couple of years now which we got second hand, 6 months ago he has blown the motor ( Burning type smell and smoke coming from it) We have been unsure about getting it fixed because of the cost of the new motor. Would this be sellable without been repaired and anyone got any idea of price that we could sell for . It worked fine before this happened and my son has had a growth spurt so no longer any good. It also has the boost battery. Cheers

hi guys, first posting but Ive recently purchased a 16'' 36v for my lad and Im considering fitting a foot brake - feel it would be more benificial for his future riding with a clutch. Anybody have any experience or suggestions on how to proceed with that? cheers Ben

A wee Oset story. My 11 year old moved up to a Beta 80 at Christmas so the Oset 20r was def surplus. He'd been on a borrowed ty 80 lately as a stopgap the last few months and how can I say ruined it and I had to return it to a friend (probably ex) Anyway first club trial I really fancied my chances against junior on the wee Oset. Now bearing in mind I don't think he ever finished a Trial on the Oset as it's on lead acids I thought my 40 years experience would offset the disadvantage of my 12.5 stone. All went well matching him mark for mark until a small hillclimb, no way I had to ride it like a caterpiller on steroids just to keep moving. S…

Hi all - We just picked up one of the 12.5" models for our 3 year old after months (and months and months) of searching for a gently used bike. The rear tire is flat and needs a new tube, I know Oset sells 'em on their site, but I was hoping to get one at a local bike shop and not wait for shipping. That said, I don't know what tube to get - there are multiple widths available...12.5 x 1.75, 12.5 x 2.25, 12.5 x 2.5...etc. I know the rim width is 2.4"...not sure which tube to get. Thanks in advance for any help

Hi the bolt/screw that holds the sprocket on keeps coming lose on all our Osets have a 16-20R and 24R have cleaned thread with brake cleaner so it’s oil free and used lock tight still seems to come lose alough never seems to come right out ! , has anyone else had this problem if so is there a answer thanks

I know its been asked a few times before but can anyone let me know which make and model grips that have the smallest grip cos my little boy has tiny hands that will directly replace the original ones. Many thanks in advance

Please excuse my english - I am from Austria. Since yesterday my 6 year old son is the proud owner of a OSET 16.0. But I am a bit confused about the charging instructions. The english manual states the following: "Always connect the charger to the AC power source before connecting the charger to the bike" "Always disconnect the charger from the bike before disconnecting the charger from the AC power source" My "german" manual tells me the exact opposite: "Always connect the charger to the bike before connecting the charger to the AC power source" "Always disconnect the charger from the AC power source before disconnecting the charger from the bike" Question: What…

Hi everyone!! sorry for bother you with this old issue, but i noted that you guys knows a lot about this...i want to upgrade the battery and after reading a lot ...still not sure if my solution it will work....: i would use 4 x High Capacity 20000mAh 4S 12C Lipo Pack.... my questions are: 1.- are they power enough? (i ask, because you explained in other thread that maybe dont release the spected power for a 20r oset) 2.- I 've read a lot about built in BMS...this packs doesnt have built in BMS ....it enough with the charger have some kind of BMS ? (for balance charge, voltage protect etc) or you recomend buy something else for battery monitoring? …

Can anyone shed some light on what the 3rd pin on the Oset charger does. I see there is no voltage on the charger when unplugged but once plugged in, there must be some comms over that 3rd pin that enables the charger output. Any ideas?

Hi has anyone got a seat/mudguard unit for this model kicking around Thanks Mark

replaced the stock Oset 24r controller with a different model. installed potentiometers on the throttle's +5v and ground wire, and tweaked them until I managed to tame the acceleration to my liking, and vanish the dead band of the throttle, when applying power. measured the max amp draw at full throttle from stand still on a high traction surface (no wheel spin) - 55 amps. is this reasonable for this model? too low? too high?

Hi, my son managed to outlast the batteries on his 12.5 Oset yesterday so I'm considering getting him some spare ones. These are the options I have:- (i) ones from Oset, say they are 8Ah, can see from the picture they are Ritar brand for
