OSET Electric Trials Bikes

Hi All, Hoping for a little wisdom. My lads 20" stopped running the other day after riding with the rear brake dragging a little. Anyway, the current situation is, the keyswitch powers on the throttle LED's showing full power but the relay doesn't click. I've checked the switch feed to the relay and I don't see any voltage. The switch feed seems to originate from the controller, so my only thought is that the controller is goosed. I've also tried another set of batteries just in case they are on low charge. Any other thoughts? Cheers, Wayne.

Hi guys My boy (2.5yrs) is a true trials rider. He HAS TO ride through every bit of mud he can find. How do I clean his bike? Im presuming that I cant hose the bike down due to the electronics. Please dont say use a toothbrush.

Hi guys, Just picked up a 2010 Oset 16 36V and noticed an intermittent problem. When the motor is running full open throttle or if the bike is slowing down there is a rubbing noise coming from the motor. It doesn't seem to happen when getting up to speed. First I thought it was from the chain against the plastic casing but in fact its coming from the motor. The sound isn't loud, and initial instinct was a wheel bearing, but is definiately coming from the motor. There doesn't seem to be any play in the bearings as rotation and chain tension seem fine. Has anyone else had a similar problem or any advise before stripping the motor? Also are these motors easy to split…

Hi All Having recently read in the advert for Oset about 4yr olds being allowed to run on these bikes under new ACU rules, I was wondering if any clubs have taken this up. I am based in Devon and have just bought a 16 36v and a 12.5 for my 4 boys to practice on. My boys are between 6 and 1 (may be a short while before the 1yr old rides one). Also do they need ACU approved helmets or are cycle helmets Ok. Also does anyone know how clubs generally feel about them following you around between sections (once they are competant on the bikes). Sorry for all the questions, but getting back into trials after a 20ish yr lay off. Many thanks Andy

Hi guys , just brought my 2 sons for xmas oset bikes, 16 r and a 20 r, and was wondering what is the law about riding them in the forest, I've looked on the forestry commission site and can't find anything , basically I will ride my mountain bike and I will try and keep up with them lol

Here are the instructions, this should give most of the details that are needed to decide. Throttle Tamer Instructions V1.0.pdf It is a inline device that fits between the throttle and controller. Here are also a couple of pictures of the device. Please be aware that I do not make these or sell these devices, I just think that It may be a good solution to a problem that some are having with throttle control on electric bikes.

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?

hi, i was thinking of replacing the handle bars, (for higher ones) and the grips too, any idea which ones to get, also i want to change the lever for the front brake for an longer one as the original doesn`t seem long enough because of the accelerater, not sure what to get though ? any advice would be great !

hi there , i just bought my son a 2016 OSET 16 and need to get new batteries. anyone have advice / info for a battery upgrade? where they bought how much, installations etc i am new to all this and learning, want better performance and batteries to last more than 40 mins etc. https://www.kijiji.ca/v-ebike/kitchener-waterloo/ebike-36v-10ah-lithium-ion-with-bms/1495463918?undefined would this battery work well? Ebike 36v 10ah lithium ion with bms for 180$ cash said it was charged 10 times any advice is really appreciated. trying to keep costs lower i know these are expensive Also I am looking for an adult electric OSET…

Hi all, Could anyone tell me how much these bikes are new?? I'd like to get one for my sons birthday in march and be good to have a idea of the cost? What they go for second hand? not that I can find one anywhere.........

Oset 16: The batteries are flat (only one red light on handle bar indicator and the bike has no riding power). When i plugged the charging in the charging socket on the bike with the bike turned off, then turned the charger on the green light came on, but it has allows shown a red light when the batteries are flat? Using a multi meter i tested the charge current coming out of the charger, result 28.2 volts. I then tested the charge coming from the pos and neg leads coming from the bike to the batteries, result 28.2 volts. I then tested the link cable between both batteries and this sounded out okay. I then tested the volted with the link between both batteries connected, …

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…

Just interested in how old people's kids are when they start riding an oset 12.5?? I'm forward planning ( saving money ) for my boys 2nd birthday ( next year ). Just thought I'd enquire the average age of kids getting started and does anyone use stabilisers to start them off?? He's on a balance bike already at 14 months and loves watching me on my 4rt and trials DVDs, so I would like to get him started as soon as I can.

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.

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…

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…

I put this here rather than in the trials gear section due to it aimed more towards oset sized children. I've took the plunge and ordered a 12.5 oset, will take delivery in a week and a half.. But now the hard part in sourcing the kit to protect him. I need to find a trials helmet small enough to fit on my 25 month old son's head. He is quite big for his age I would say, although I've yet to look at his bike helmet size I just want to know what helmets you guys use and the smallest fitting? My local dealer stocks wulf sport, and their smallest size is 54cm.. I think that may be a little too big, is there any smaller sizes such as xxs? As for armour, would you recome…

Hi has anyone got a wiring diagram for a 2009/10 12.5 oset please Thanks

Ok... so I made the mistake of "Just going to do one thing..." to Gavin's OSET.. The Mod bug can happen any time anywhere.. Here's how it started.. Then I added Bars and Grips.. Then it happened.. I just started to change the back wheel... More to come later today

Hi all just wondering just purchased a oset 16 36 v brilliant bit a kit for my boy he loves it but noticed the charger is flashing red and yellow is this normal and is there a fast charger I can buy or a battery upgrade for longer riding many thanks Dan
