OSET Electric Trials Bikes

  1. Started by Erwin S,

    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

  2. I'm looking at these bikes used and haven't been able to find many answers about this. I see used bikes listed at around $3,500. From what little info I could find, the battery packs cost $800-1,200 and wear out in a few years. If that is true, that price isnt really a discount if the bike is a couple years old. Is that info accurate? Also is the battery pack easily swappable? Seems like that would be a nice way to keep riding vs putting it up for the day. Thanks.

    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.

    Hi all Newbie here - to both trails & Oset. Bought a 2nd hand 2017 24 R privately. Just gone to charge it, red light comes on on the charger but not the yellow one as it should have as the bike battery is flat. I try to pull off the charger plug lead from the battery socket (after unscrewing the locking ring)& the charger plug on the lead comes apart in my hand !!!! DOHHHH !!!! The plastic cap & metal 'plug' in the lead have separated with all 4 wires detaching from the 'prongs' in the metal body of the charger lead plug. Anyone know of someone who can repair it please or any other recommendations,,,,,,,,,,,,,, Many thanks …

    Have brought the Shenko “19” 3.50 back tyre to put on my 24 Oset haven’t fitted it yet and just wondering if I could have some thoughts on this the Shenko was $30.00 as opposed to $600.00 for the 17 inch wheel and wider trials tyre from Oset , I only use the bike for trials and it’s great but looses a bit of grip with stock tyre, would I be better off with the 17 from oset or the Shenko, the Shenko will change the gearing a bit !!!!

    Hi all. I have a 2017 Oset 24R and i would like to get more power from it. Any suggestions? I am not averse to ripping the entire motor and controller set up out and starting again. I would like more range, but definitely more torque. Thanks guys.

    Hi all, I've recently bought a 2nd hand 20 racing, I believe 2016, when you open the throttle there is a very slight hesitation, its all the way through the range and adjusting the response doesn't seem to get rid of it, is this normal? my son doesn't seem notice it but it is there and must be hindering his riding. Also how to people wash their bikes? I've been told a jet wash isn't the thing to do. thanks for any help Wayne

    Hi All, My son has a Oset 20 Racing, I believe it’s a 2016. He’s been competing in schoolboys events for approx. 6 months on the bike, the club has acquired a new piece of ground which has more hills. We went to a trial last Saturday at this new venue. When my son opened the throttle the bike accelerates as it should and he was carrying enough speed to easily reach the top, but when he’s nearing the top of the hill the bike completely cuts out, no power at all and he falls off, when I picked him up the bike worked completely as normal. All it needed to "reset" was to close throttle. The bike did this on every largish hill for the next 4 sections, event…

    Bit of background first my son is 8 and has been riding autos since he was about 3. A few months back we got a 2018 oset 20r which has a boost bikes Lipo battery. Trouble is we are finding it REALLY hard to get to grips with the bike, I've ridden it myself and can see where he's coming from. I know it's not a petrol bike so it will be different but I will try to explain the problem... Its all to do with the throttle control and how the power surges very quickly with no build up whatsoever. There is also a good 1 second gap between hitting the throttle and movement at the rear wheel... This is the biggest problem. It makes any kind of slow, technical riding rea…

    Hi, just tried to connect an oset lanyard to my son 16”. I tried a petrol bike one and that was working backwards, so changed it for a Oset one. now, when I connect it it does not work at all, why is that? What I did was removing the key switch which was not needed and connected the two wires straight into the lanyard wires. shoulnt the oset lanyard close a circuit between the two wires when it’s clipped on? what am I missing? the bike is an older model equipped with Kelly controller and OEM throttle

    Hi all, first of all, I apologize for my poor english, I'm french ;-) I've just bought a 20 R to my 8 year old son, He really enjoy it all day long, but it's really long to have to recharge every 45 mn of use for 2H, then I have tried to understand all what you write about LIPO...with my poor english and my very poor knowing in electric system. For resume, Is anyone could tell me the simple way (and safer) to do this upgrade, and the gain we'll have. Thanks

    Hi All My son got a OSET 12.5 (think it’s a 2010 model). The front fork is pretty stiff, and I was thinking on taking It apart, to do a bit of refurb on it. I do know that it’s just springs and no oil, but I still think I could do something (maybe change springs). But it does not seems like you can take the fork apart= Does any of you guys have any good advice – have any of you taken the bloody thing apart? Regards Thoams

    Hi all, I've just bought an non running Oset 16 36v 2012 model I think. I got it to work for about 5 seconds, but now nothing. When I turn the key switch on the relay clicks and soon after the controller clicks. I'm fairly sure the batteries are good and I have three red lights on the handlebar. As soon as I turn the throttle the motor will clunk a bit and then nothing. All the connections seem ok, I've read loads of stuff about measuring voltage on the relay and controller but my relay is all sealed and not really sure what I'm doing anyway. The motor seems quite clunky when I rotate it from turning the wheel, is this normal? guessing I will ne…
