Introduction: Motorized Drift Trike!!!
If you haven't heard of the new craze called drift triking then you are missing out!
A drift trike consists of a tricycle with a pneumatic front wheel and hard plastic rear wheels.
The front wheel can have a freewheeling crank or foot pegs

Step 1: History
Drift Trikes are tricycles that have slick rear wheels, normally made from a hard plastic material. They are usually ridden on paved roads with a steep downhill gradient and some corners. Smooth roads are preferred to coarse chip sealed road as coarse surfaces tend to wear rear wheels faster.
Riders gather momentum through gravity, although some drift trikes have pedals. Pedals are useful for slow speed riding, but are of no use at high speed. Drift trikes can reach speeds of up to 90km/h, but the normal operating speed is between 25 and 65km/h.
Drift trikes have come along way, one of the first mass produced trike was the Huffy slider as pictured.
Many people upgrade huffy sliders where as some build them from scratch. In this instructable I will be using the front end from the slider and building a bolt on MOTORIZED rear end.
Most of the parts can be bought bought from the hardware and the rest from eBay.
Step 2: Part List
I have split the parts up into where I bought them
1x m16 threaded rod (Found with the nuts and bolts usually, length is approx 1m
10x m16 nuts
2x 1m lengths of 30x30mm steel stock
1x 1m length of 20mm steel angle
Various nuts and bolts
1x 49cc pocket bike engine with clutch (eBay) known as a cag engine
1x Pocket bike muffler
1x 7 tooth pinion 25h
1x 62 tooth sprocket 25h
1x 25h chain
Bearing store 2x 16mm pillow block bearings
I was able to find some things around the house including fuel tank, fuel line and chain tensioner
Step 3: Rear Frame
The rear frame is made from the 30x30 steel stock welded together in a very basic shape.
(This was my first time welding and I managed)
The measurements shown are what I did, they can easily be changed to meet your requirements.
Step 4: Axle Setup
The axle (threaded rod) was mounted to the frame through 2 pillow block bearings.
My bearings had mounting holes 80mm apart and were centred on the frame.
Once these are bolted on, the axle can be mounted
I went with the configuration of
m16 nut, m16 nut, wheel, m16 nut, PILLOW BLOCK, m16 nut, space m16 nut, wheel hub, sprocket, wheel hub, m16 nut, space , m16 nut, PILLOW BLOCK, m16 nut, wheel, m16 nut, m16 nut,
Step 5: Engine Mounting/alignment
All engines will have a different mounting pattern but the same technique can be used
I used angle iron as seen in the diagram and cut 30mm off each end from one surface so it would sit on the frame.
I approximated the alignment and
Clamped, tacked, welded
Later on when adding the chain, the sprocket can be finely adjusted into alignment by moving the nuts up/down the thread.
Step 6: Wheel Setup
The wheels used were 10 inch in diameter and had a 16mm bore.
They were fixed to the axle by clamping down nuts on either side EXTREMELY HARD.
To be able to drift, the rubber wheels must be sleeved in plastic
at first I was unable to find PVC that suited so I was originally using huffy slider wheels cut open.
I then picked up an off cut of 225mm PVC for $30 which is a LOT slipperier.
How to get sleeves on wheels
1. Deflate wheels
2. Force sleeve over tire (Use tire leavers, flat screw drivers ect)
3. Inflate tire
In my opinion, the best way of cutting sleeves is using an angle grinder.
1. Clamp angle grinder to bench
2. Stand PVC up and feed through cutting blade
THIS PRODUCES EXTREMELY FINE DUST BE CAREFUL!
Step 7: Other Bits and Pieces
Cut chain to size, I did not have a chain break but did have a joiner link so I got away with using and angle grinder to grind the head of the pin off and rejoining it with the joining link.
Chain is run over sprockets and joined, using spanners, fine tune the alignment by moving the sprocket over to straighten the path of the chain
A basic bike chain tensioner was welded in alignment with the chain and can be slid up and down to ajust chain tension.
Exhaust was bought online and developed more power and sounded a LOT better
The fuel tank in the picture is a drink bottle which I do not recommend as it is not rated for fuel.
It has since been changed to a lawnmower tank I got for free from a mower shop
I used a standard throttle cable hooked up to a brake lever on the right hand side of the handlebars. I found this better than twist throttle due to the amount of turning you do and how this affects the throttle.
Step 8: Finished Product
It tops out at 40km/h which feels really fast on a kids tricycle.
If I was to redo it, I would user heavier duty sprocket/chain combos and would build it in a cleaner matter.
It works really well! and is extremely fun!
The video below does not do it justice! Being on it, drifting and holding corners is a huge thrill.
I will upload a properly edited video when I have time but I rushed this instructable as I wanted to enter it in 2 competitions
