I got a new trike a week ago and decided to motorize it with a 500w 24v electric wheelchair motor i had in the shed. Top speed is about 15mph and range is about 20 miles on a charge.
Step 1: Parts and Tools.
A trike! I got mine at the local wally world for around 250 USD.
Electric wheelchair motor with gearbox.I like wheelchair motors because they usually have a gearbox on the motor that turns the output shaft 90 degrees. The gearbox also reduces the shaft speed down from 2500RPM to around 200RPM. This matches the speed of a bicyclist peddling so you can use the original bike gearing.
Bicycle sprocket.I used a rear sprocket off of a kids bike. Removing the sprocket from the coaster brake assembly was really easy. If you use a large sprocket you get more speed. I used a smaller sprocket so i can get massive torque to climb hills.
Batteries.The motor i have is 24 volt. I used two 12v 50ah batteries for this project. Since the batteries are wired in a 24v configuration i have a 24v pack with 50ah of storage. The batteries i use are heavy but cheap lead acid batteries. Look for a local place that remanufactures batteries, it will cost much less.
Speed controller PWM.I used this controller from Amazon. Speed controller linkIt can provide a 1440w @ 24v and since the motor only pulls 500w it should hold up to the abuse i will put it through.
Circuit breaker or fuses.FOR SAFETY! With this much storage capacity and amperage you want to be as safe as possible. I use a 50amp breaker placed between the battery packs.
Some 5 or 7 strand thermostat wire.Use this to extend the wires on the speed control switch to make it reach the handlebars.
Wire and connectors.You will need some thick wire to run the battery leads to the controller. Use wire connectors to hook everything up and make it look clean.
Zip Ties.To keep wires in place and you can never have too many zip ties.
The tools required for this project will vary. If you have a cordless drill and a basic set of tools you should be good.
The only part that may be tricky for some people is welding the sprocket to the wheelchair motor hub. If you have a local mechanic, muffler shop, high school metal shop, or somewhere that has a welder just offer an employee 10 or 20 bucks to weld it. The job will take 10 minutes and they get some lunch money.
Step 2: Mounting the Motor
Figuring out how and where to mount the motor is always the hardest part. This new trike has a very wide rear fork. I managed to slip the motor right in and it lines up with the rear gear perfectly. The plates i used were the original mounting brackets from the wheelchair the motor came from. They are basically flat bits of aluminum with holes in them. The plates are bolted to the gearbox and then bolted to the bike frame.
Step 3: Making the Drive Sprocket and Connecting the Drive Chain.
The wheelchair motor i have came with a hub to mount to the original wheelchair wheel. On the end of the hub i welded a sprocket from a kids bicycle.
When you make this hub you need to make sure the sprocket is on straight so it does not wobble around when the motor is running or the chain will fall off. Take your time and do it right. Make sure the welds are strong.Try putting the hub on the motor and powering the motor with a small battery. This will help position the sprocket before welding.
This setup deletes the front pedals from the drive chain. I have ordered a front sprocket with a freewheel clutch inside it so the pedals do not spin when the motor is running. I originally tried the setup with the front connected but it led to me getting my shins whacked every time i stopped peddling with the motor on.
This bike is a 7 speed and all the gears work. 1st gear only goes 5mph but will climb very steep hills. 7th gear tops out around 15 to 17mph. The multiple gears helps control speed, torque, and motor load/temp.
Step 4: Wiring Up the Electrics.
This is simple. the and. from the battery pack go to the B and B- on the controller. Make sure from the battery goes to B and the. from the battery goes to B-. If you reverse the polarity of the B and B- on the controller it will short out immediately and you will be placing another amazon order.
The speed control knob that comes with the board needs the wires lengthened so you can place it on the handlebars. Use the thermostat wire to lengthen the wire.
Connect the motor to the M and M- on the controller. The way my motor is placed in the bike i need to run the motor backwards. So i flipped the M and M- and it spins the correct direction.
Step 5: Battery Basket.
The two batteries i used fit perfectly in the basket only taking up the front half. I cut some plywood boards to place in the bottom of the basket and lined the basket with rag rugs from the dollar store. A little upholstery foam makes good padding for the sides of the batteries so they don’t rattle around. All the battery weight is placed directly on the rear axle which helps with balance.
To cover the back half of the basket i got a board, drilled holes in the end of it, and zip tied it to the basket using the zip ties as the hinge.
Step 6: Stuff You Should Carry With You.
Trial and error goes hand in hand with building your own stuff. It is a good idea to keep some tools with you to fix the bike if you break down.
Standard pliers.Most useful tool.
Various wrenches.For undoing just about every nut and bolt on the bike.
Needle nose pliers.For small stuff
Chain tool.Handy but not essential
Hex wrench. For the motor mounting plate bolts.
Large adjustable pliers.For rounding off nuts and bolts in fits of rage.
Wire cutters.For cutting wires and zip tie tails.
Electrical tape.Its tape! It fixes most things for 5 or so minutes.
Zip ties.Because tape cant fix everything.
Bike lock, Battery charger, Extension Cord.To secure the bike and also recharge the battery where an outlet can be had.
Step 7: Accessories and a Ride.
You should always have lights on your bike. A bright headlight for the front and a blinking red light for the rear.
I have also added a short distance light to my handlebars because the streets in my area are really bad. The short range light helps me see bumps and holes.
Phone holder. This is great for installing an old phone for speed/mileage tracking and maps/navigation. I have an old S3 that i run Goodle maps on (download offline maps) and DigiHUD speedometer. They both use GPS to get location so no cell service is required. Maps are downloaded and updated on Wi-Fi.

I really enjoyed this concept because a year ago I decided to trash my mowbot project where I used 2 wheelchair motors to power the chassis of a push mower using a controller with wireless remote control It was fun but not exactly practical due to the difficulty of steering it. I ended up spending more time trying to learn to control it than actually getting the lawn mowed. So. I want to use those same motors and batteries which are exactly what you used for this tricycle. I wish I had a tricycle but just have a 7 speed bicycle I would like to convert. The 2 most challenging parts for me are figuring how to mount one or both of these motors. They do NOT have a gearbox. I may have to puchase one to accomodate the rpm reduction. Also just ligning up the welded sprocket. I have all of the welding equipment but have never had the nerve to actually try it. I did attend a welding class a while back so know how to be careful. I also don’t know the ability of my home/garage circuit will handle it. I guess this kind of stuff you just have to start getting your hands on and solve each problem as it comes. Again, good job and it inspires me to try more at my project.
without seeing your Etrike, ive just brought a new £190 24inch (cheaper than 26) 7 speed trike and used one of 2 24v motors with gearbox, removed the electric brake, they fitted on front left and right 14inch wheels, bolted direct to the wheel, so they have to be safe and torque wise to pull someone that could be large reliably, but i split a peddle sprocket leaving a bit of the 4 spoke/bars that hold it together, drilled and added extra rivits, then centred it to the motor drive hub and drilled and bolted it on, how the wheel was originally, then made a plate with holes to match the gearbox holes, and 3 to fit ones on the frame and tightened these ,the 4 i put long bolts with nuts in between plate and motor so i can adjust the tilt and get it straight with the rear sprocket and gear, after a few other tries this was best, i did try a ebike mid-drive ? gear/sprocket thing i found on a bent up dumped ebike with a razor e100 motor but it was just a slight peddle assist, the wheelchair motor is perfect, i have another and i found them and the joy stick, controller on a near complete Wchair free, now i no it works i might put a controller and throttle on it, im just running it using 2 12v re-lemond lead batteries, that go to a old 24v drill trigger/switch then to the motor, if it was a fixed wheel i could have reverse using this to, i could put the other motr on but geared and wired to start when the first has pulled off and maxed out, that way it should go faster further from a smaller lighter cooler less friction so far longer lasting set up all round, after saying that it dawn n me that if that is the case, it could produce its own power and go for miles, lol another sleepless night cogs spinning somewhere, i need a test for ADHD, cheers all
Super job! I just have a couple of questions:
What about the weight of the batteries, do they slow down the bike at all?
Since an electric wheelchair only has one speed, how do you convert that motor to have a varying speed?
Thanks again. I am trying to figure out how I can cheaply make my bicycle and electric bike as I have really bad knees but want to ride my bike with the assist of the electric motor.
sorry it took so long for me to reply!
Yes batteries are super heavy. If i had the money i would go to something NOT lead based. Since the bike is geared for pulling power i can hit 17mph. if i geared it for speed the batteries would be a huge issue weighing in at 35lbs each.

Icaro 2000 electric Pit-trike
Icaro 2000, one of the most important hang glider manufacturers in the world, has extended its range with a single-seat light trike, which can be used with a conventional hang glider and a lightweight engine for a totally new dimension of flight.
The Icaro 2000 Pit-trike is available only in a futuristic electric version.
The HPD (High Power Direct) motor was developed by Werner Eck and is distributed by Flytec. It is a brushless, rotating-can motor which directly powers a 1.4 m diameter folding-blade propeller, with no reduction gear.
Flytec HPD 10 10 kw Electronic system Flytec MMS 10 Weight 5 kg
For further details on the electric motor, see the following websites:
The motor is regulated by the MMS system (Motor Management System).
An advanced control system prevents accidental motor activation. If essential parameters are exceeded, the power supplied is automatically reduced, and the pilot is informed of the problem by means of an error message on the control interface.
The motor’s functioning is constantly monitored by an interface that displays all operational parameters, such as voltage, power in amp-hours, current absorption, motor temperature, the Motor Management System, the state of the accumulators, and so forth.
Various accumulator systems are available.
The standard accumulator is a 24 Ah lithium ion model, providing a flight time of about 20 minutes with an RX18 or RX21 wing and an 80 kg pilot.
Two batteries connected in parallel (48 Ah) provide a flight time of 40 minutes.
Using a modern Rapid-charge lithium polymer accumulator, flight time can be extended to about 30 minutes, or up to one hour’s flight when two of these accumulators are connected in parallel, providing a total of 80 Ah.
The maximum flight time varies according to pilot weight, the style of flying, and the surface area of the wing.
3 Flytec batteries type are available:
LiIon 24 Ah 12,5 kg LiPo 40 Ah 16 kg LiPo 60 Ah 22 kg
The folding-blade propeller in carbon fibre was specially developed for the electric motor.
It has a diameter of 1.4 metres, and it guarantees high propulsive efficiency.
The most suitable hang glider
Just about any normal hang glider can be used with Icaro 2000’s Pit-trike, ensuring that the total weight of the system (trike, wing, pilot) does not exceed the maximum certified weight for the wing in question.
Icaro 2000 recommends two sizes of hang glider for the Pit-trike.
The simplest hang glider in Icaro 2000’s range, the RX, in RX 18 or RX 21 versions, is ideal for enjoyable and stress-free flying. This glider’s size and characteristics make it ideal for beginners.
For professional pilots, Icaro 2000 recommends the MastR, in size L.
