OSET Electric Trials Bikes

Hi,can anybody shed some light on where I should start with my sons 07 24v 16 oset, it dos'nt seem to have the same power as his 12.5. I fitted a new set of batteries and this has made a great difference to the length of time he can ride but the actual power the motor puts out for him getting up climbs etc seems to be lacking. Ive tried disconnecting the limiter but this makes no difference, I'm now thinking,new brushesin the motor or a new motor? Can anybody point me in the right direction or had a similar problem? THANKS

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?

So I put a new bearing in my oset 16 36v motor 2012 and now it runs in reverse. What might I of done wrong?? I had both sides of the motor off, it was tricky putting the 4 springy things back on (technical term there), I think they all went on properly and as far as I was concerned I didn't touch or change any wires??.......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

Has anyone fit a rear brake foot pedal on an oset 24? I was looking at getting one but I am a little thrown off by the hand brake levers for the rear.

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!

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

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

Hi I am new to this forum and trials in general, I normally ride enduro or rally raids. I have ended up here because; My eldest son (6 years old) moved up from a PeeWee to a Beta Mini trial, this meant his little brother (3 n a bit) could inherit the PeeWee. Unfortunately the youngest is very small and can not manage the PeeWee, then I spotted one of the 12.5's at a Surrey School Boys events a couple of weeks ago. It was 50/50 between putting up with the PeeWee or getting an Oset until I found this forum, reading back through the messages made up my mind we now have a new 07 12.5 being delivered for Christmas. This is either going to be magical or war as the Beta…

Hi All, Just got my lads (aged 4 and 7) an Oset 16.0. All is going well, but..... the diameter of the grips is M-A-S-S-I-V-E. I can hardly get my hands round them! Has anyone used any [smaller] alternatives??? Ta, David

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, I'm Travis, got my son, Adler, a 12.5 about 9 months ago. He was 2 yrs 9 months when we got it. We had just removed the training wheels on his 12" bicycle a week or so before the Oset arrived. He is now 3.5 yrs. I have a small bicycle shop in Louisiana, USA. Also have a very small fab shop in back set up for small volume frame building. Right out the box it weighed 51lbs. Immediately changed: -Bars and stem to 31.8 clamp MTB stuff. -Swapped brake cables to teflon coated wires with shorter lined housing. Better Pads. Very shortly swapped the whole front assembly for a cheap Avid one, HUGE improvement. Removed one of the springs from the rear brake to lighten the ac…

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 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 all sorry to repeat a subject that has probably been covered many times. Same issue as most really... Want to remove the throttle lag and smooth out power delivery on oset 12.5. I see there are a number of different solutions available (none from oset which is surprising) has anyone used a torque control module from pico amps? http://www.automotive.picoamps.de/en/download_en.htm http://www.automotive.picoamps.de/doc/TorqueModuleOSET.pdf Seems a little steep at 129 plus vat. If anyone has any experience or recommendations I would really appreciate it Cheers Michael

I signed up for newsletter updates on the Oset site. The 24 looks great but I'm having a hard time figuring out the size compared a full-sized bike. I suppose 24 means 24" wheels? Although it looks like the rear is running a full size trials tire. "The OSET 24.0 development program is gaining pace. We are waiting on several important test parts to take the project closer to production, but currently have four test bikes being used by a variety of riders in a variety of situations. Reaction to the bikes has been universally positive, with the performance continuing to surprise and amaze! The 24.0 will be an important addition to the range and introduc…

Hi guys I have just purchased the above bike and would like to slow it down a little bit until my daughter gets to grips with it. What can I do?

I just bought a used Oset 12.5R for son #2 (shhhh, Xmas present). Needs new ti res. The stock tires are 12x2.4 (64-203mm). There are some smokin' deals on ebay for tires labeled 12 1/2" x 2 1/4". Two tires and two tubes for $23 shipped. Will 12.5" tires fit and is this why the bike model is a 12.5?

My sons Oset recently lost all power, the problem was traced to the relay mounted under the rear fender, there was voltage across the two small spade terminal wires entering but nothing on the main switch wires and no audible "click" when switching on. Although this appeared well protected being shrink wrapped in plastic and housed in a velcro pouch, on removal it was found to be open to the elements where the wires entered the wrapping and I was surprised to see that the contacts for the switch were visible through a large opening in the relay body, I.e open to the elements themselves. Wd40 sprayed into the relay and it worked again. I have ordered a replacement incase …
