Been chasing the idea of getting a light weight mx suspended electric moto for single track and hard enduro type conditions.
Started back in 2020 when had the chance to demo an electric motion epure and was blown away by the torque, weight, and the ability to hear while riding.
Plus easy maintenance.
Should have just gotten an escape and been done with it but was chasing a similar ride as my old 06 yz144.
Started with trying to convert a gas gas trials to electric and was awaiting for a kit from ETA but no kit was released.
Got tired of waiting and grabbed a KTM Freeride electric.
KTM was nice but a fatty at 245lbs and was seeking something in the 200-210 range like a 125cc weight.
Hated the 12v battery set up it had and top heavy feel.
Picked up a 23 Mecatecno Dragonfly and that scratched the itch for a while.
Wanted a more faster trail weapon and was looking at an ultra bee or put a deposit down on a Cake Bukk.
Waited and after the second delay asked for my deposit back as sensed something was up. Got my deposit back.
Then was hopeful for the Dust Hightail but that seemed bits out at the time so went and tried to purchase a Eduro from Austria.
Paid for a Eduro frame kit in 2024 and nothing has showed up yet.
David Friedinger was the owner/maker of the Eduro which is now Jarv-e.
The Eduro thing is for another topic.
After that crap started to look at a Varg but hated the weight at 270lbs.
Then started assessing mx conversions as noticed the space was becoming standardized with kits from E&C and QS/Fardriver set ups.
Was looking at converting a yz into a yz-e with the E&C kit but waited until the kits were in the wild and people could share about the weight and power.
Had that percolating in the background as an option but saw other diy conversions that started using x9000.
Peeked my interest as wanted a more “apple” experience for controller tuning as I am a newbie.
Started looking at dirt bike rollers and chassis.
Always wanted a TM and was close to buying a 125 back in 2018 but was hesitant about parts.
At the same time checking out chassis stuff got the bright idea of taking a factor-e drivetrain with 18kw and stuffing it into a full,size.
Something EM wasn’t planning to do anytime soon.
Found a 22 TM 300 Enduro in ok shape for a good price and was planning to go either stuffing the EM Factor-e drivetrain and going QS/x9000 route.
Picked up a factor-e used and tried fitting the drivetrain.
Of course didn’t fit and the stock battery could not be fitted in any way into the chassis after placing the gearbox.
Swingarm hole was 14mm not 16mm like full size and couldn’t make gearbox sit flat.
If was to attempt again would go with YZ-f chassis like the 14-17 as those frame space looks huge.
Put the factor-e back together and sold it.
After the attempt went with plan b - qs138 v3 70h/x9000 v3/surron light bee batteries.
Went with surron light bee batteries due to weight, size, and abundance of used and new options available locally.
Ordered custom mounts from Lithium King and got motor fitted as titght as possible to stock sprocket location,
Then stared at the frame for a long time and made various cardboard battery Amorge battery sizes to see what would be the best fitting.
Saw a CRF conversion on FB group and liked the battery box design.
Worked with Lithium King in the design and measurements needed for the TM.
Did a version in clear lexan plastic to test fit which allowed to see where the holes were and stuff.
Suggested some adjustments to better fit and line up.
With V2 designed went ahead and got the sides done in 5mm 7075 and the front,back, and bottom in ss316.
V2.5 would be adding slits for the front, back, and bottom plates so no bending would be needed.
That would about 2.5 to 3lbs of weight with the swap from ss316 to 7075.
Below are pics of EM Factor-e drive train resting in the tm frame, various stages of the TM conversion.
Right now waiting on wire insulation and lugs and need to bleed rear brake, install chain, final brackets for connecting top frame mount to battery cage,and decals.
So super close.
Weight as been a focus as I chase 125cc weight.
The TM roller chsssis got it down to 125lbs before any electric conversion parts.
Now at 175lbs with chain (through chain and its box on the seat when weighing).
So 175lbs before battery and got two 72v P42B packs each weighing 35lbs.
Right at 210lbs and safer to say 211lbs.
Was really hoping for sub-200lbs but it’s a journey.
As stated above got future weight saving possibilities.
Throughout the build did some weight saving type mods and there are not much for a TM.
As the nice thing with the TM chassis it was easy to work on, and lot of the stuff was designed on being light weight already.
Shooting for maybe this weekend if everything needed shows up and if friend will be available to assist in the cutting of the motor phase wires, putting on new lugs, and tuning.
Will circle around after I get a chance for a rip.
