DIY front fork for 2wd scooter/ drift trike.

[Ianhill]

Edit
This fork and frame could equally be cut up and mount a 148mm hub from qs motor to make a sweet 4kw drift trike, torque arm will have to be added to the fork but it's beefy enough to take it got the option of mounting from a 20 to 26 inch rim and shortening the leg if needed while incorporating the torque arm with stainless to alu bolted joint simular to the drawing below.


After doing some research on the differing standards for mountain bikes and stunt/dirt scooters I've come to conclusion that a solid front end could be made from combining the best of the two to make a custom fork from easily obtainable parts to mount a dualtron hub.

Handlebars:- SCS oversize cromoly/titanium

Clamp:- scs 8mm clamp bolts 7075 alu

Headtube:- Salvage a tapered headtube with internal bearing cups from an aluminium mountain bike and the matching headset

Fork:- Fatbike aluminium 150mm dropout tapered steerer fork that needs to be shortened, blocks welded to the bottom to form a dropout clamp to hold the hub, A stainless sandwich plate will bolt to the bottom of the dropout to hold the hub axle and spread the load preventing the hub digging into the alu overtime + weld a disc mount back on.

That's it you have a front end that's got some beef combined with the rear hub and 20s Lipo you could easily get 70mph.

Lots of work to make something worse than a single rear hub drive. You can already do 70+ mph on a single motor.

It's as hard as you make it the motors are cheap on aliexpress reliable proven and the bike/scooter parts are too so why go against the grain ? I see it as cutting many a corner in fabricating to have a complete front end within an hour or 2 no messing about starting from scratch and the parts are plentiful so it's not cost heavy and the final product is light.

One could use a single lynch motor on a 10 inch wheel run it 92v 20kw and get close on 100mph but it won't be lightweight and the parts needed will increase the total weight drastically this is about a powerful build that don't break the bank and your back if you lift it.

100% it works !

Measured the wheel and it drops in nice, the frame is brand new but has a big shipping dent in the top tube that's not gonna effect my build so I got it dirt cheap, the fork was a little harder to get at a fair price all in all I've not paid 3 figures for the frame and forks plus I have a integrated headset that's worth £55 on it's own and I've put a new seat and handlebars on my old peddle bike thanks to the frames spares.
