OSET Electric Trials Bikes

Hello all, My 5yr old has turned a corner and has not started to ride his 12.5r! But, the battery life is terrible! Does anyone have a basic guide to a lipo conversion? - What to buy - how to wire I've had a quick look at some posts, but my mind is a little fried!!! Thanks, Scott

We purchased a second hand oset 12.5 for my 3 year old son. It has subsequently developed an issue where is cuts out and we have to turn it off and on to reset the motor when he accelerates hard from a stand still. The bike will not cut out if we hold the back wheel up and accelerate hard so it seems to be a load issue. If we help him accelerate at half throttle the bike runs fine and there is no issue. We have looked at all the wiring and replaced all the fuses on the bike that we can see but the issue persists. Has anyone encountered this issue?

Hi all just after some advice. My 3 year old has a bog standard oset 12.5. He's doing really well and enjoying it at a steady pace. However when he sets off it is so snappy and kind of jolts him. Is this normal? Or is there anything we can do to kind of smooth the power out?

GRIPS: I cut the grips off and replaced them with a bicycle inner tubes so my daughter could get her hands around it. I used an oil quart cap duct taped over the accelerator end for protection, and tied the inner tube into a knot on the left side, with cut tassles for my daughter's enjoyment of course. This also keeps dirt out of the throttle tube. GOVERNOR ACCESS: I used a heat shrinkwrap tube over the governor to extend is out because I kept losing the small screwdrivers, did not want them in my pocket while I chased my kids, messed up the dial by turning too hard, etc. Ian sent me one for free, Ian at OSET provides AAA service, hands down. Someone else mentioned…

Can anyone tell me if these will work on an oset 12.5? or does anyone have any tips on how to make it easyer for little hands that are not strong enough to pull the levers? http://www.tartybikes.co.uk/116mm_fixed_hubs/onza_sealed_disc_rear/c62p10814.html or someone else sugested magura hydrolic rim brakes. jhas anyone had any luck with these and will they fit? http://activesport.co.uk/shop/article_hs33_0000-002/Magura-HS33-Hydraulic-Single-Rim-Brakes.html?pse=coa

Hi, planning on buying my son a oset 12.5 but not to sure what one yet just wanted to no what the main diffrences are between the eco & racing and what would be the best one to go with.

Hi, my little boy is desperate to get on a trials bike and the Oset 12.5 sounds like the bike for him. He is 3'2" (38 inches) on the Oset site it says up to 46 inches so he'll be good for a while before hitting the max height on it but is there a minimum height and is he tall enough for one? Also, as an electric bike, does this mean that he can literally ride it anywhere (with me present) without me getting hassled?? Most of the time I would look to use the new ground in Milton Keynes but am thinking if we want to pop out for half an hour can we do so?? Thanks

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…

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

Having electrical problems with my lads 12.5 and need some expert advice! Here's the story so far.... The problem is that the drive is very weak and juddery and only a small amount of load on the rear wheel causes it to stall, i.e no torque. My initial thought was the motor brushes. Bike is a 2011 model and has been well used so would make sense. I've had the motor to bits before to do bearings so I set off down the route of checking these. However, I decided to direct wire the motor to the batteries before stripping it - this resulted in the motor spinning up nicely and with loads of torque so I didn't progress the motor strip. I've examined all connections and can't …

Hi See attached pics from the recent strip down of my little ones OSET it was cheap due to being left in the rain being uncared for by its first owner. It worked fine which is a testament to the bikes reliability but it needed a restoration so rather than forking out the $$$ for a new 2015 model daddy hit ebay! Rebuild pics to follow!

hello people!! I'm a owner of the second hand oset 12.5 racing 2016, and i want to change the batterys. Can you give me a links to buy a decent lead acid batterys? im from spain. I know that the oset stock batterys are 12v 10ah capacity. Do you know if I can put batterys (2x) of the12 v but with diferent capacity? 12ah, 14ah, 17ah etc..? for example this... https://es.rs-online.com/web/p/baterias-recargables-de-plomo-acido/0597841/?cm_mmc=ES-PPC-DS3A-_-google-_-DSA_ES_ES_Batteries-_-Batteries-_-DYNAMIC+SEARCH+ADS&matchtype=b&gclid=EAIaIQobChMIgaed4YL71wIVi0AbCh1_BAtuEAAYASAAEgJUDfD_BwE&gclsrc=aw.ds and do you know if th…

took ryan out on sunday for a bit of practice ready for this weekends oset cup.After 5 mins the motor started smoking then just stopped dead, stripped it down there was more mud and crap in there than was on the field, anyway cleaned it all out left to dry for a couple of days then rebuilt last nite everything was working fine till this morning, again 5mins on bike it's started smoking again he's only been on tarmac since. everything looks fine any ideas what it could be?? don't fancy it stopping after a couple of sections and having a bad tempered 4 yr old on saturday

Little boy got brand new oset 12.5 for xmas and has prob only used for 2-3 hrs max (bloody english weather), its only been used on complete flat ground and never been dropped, the problem I have noticed is the mudguard and center rear wheel arent lined up? The chain and wheel all run true but it seems the left hand side swingarm is a mm lower than the right side so when you stand back and eye the line the wheel looks like it slightly tilts to the left(lower side). I took whole back assembly of and greased and loosened the swingarm pivot and whilst back wheel was off i placed a spirit level across width swingarm and right side is slightly higher, i then loosened the 4 nut/…

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

newbie stampedes in where the wise fear to tread - but hoping for more ideas in this forum - here are my tips: 1. my 3.5 year old's hands were simply not big or strong enough to pull the brakes. 2 things changed this: i) i removed the spring at the bottom of the back brake ii) i adjusted the the little alan screws in each lever to bring the levers well within his reach. now he can use both brakes with relative ease, even if he won't be pulling stoppies any time soon. 2. i accidentally knocked the cover off the little rheostat, next to the key slot. This allows me to dial in different speeds without using a screw driver, by simply turning the dial with my finger. I…

Does anyone have information on after market tires and brake pads that will fit the Oset 12.5R? I tried searching tires online but there seems to be different tire specs depending on manufacturer. My kid loves doing burnouts and needs a new back tire soon. Was hoping to find a more aggressive tire. Thanks.

Hey guys, awsome content here on the forums. We decided to move from Estonia to Spain and the best thing about this is the weather. Our 3 year old can ride his OSET 12.5R on a daily basis enjoys every second of it. Made a small edit to youtube for friends and family to see, thought maybe I should post it here aswell and get some feedback. Enjoy (it's in Estonian but subtitled)
