Here is an electric bike kit guide that I have put together for you to help sort out what kits are available for your bicycle. Some of these kits are just for converting your current bicycle to electric and other kits will only be speced on new complete ebikes. I will continue to add to this list as I come across more ebike kits.
Electric Bike Hub Motor Kits
Hub motor kits are the “norm” these days and they are a great way to power an ebike.
Clean Republic offers one of the more economical front hub motor kits. It looks like it is very easy to install and remove if you want to return your bike to a regular bike. Use this Clean Republic coupon code to get $5 off your order: peteprebus
The Bionx electric bike kit is a very refined system that is becoming a standard kit for bike manufacturer’s to use for their electric bikes. Uses a rear hub motor design. Bionx is one of the “cleanest” electric bike conversion kits. Here are my thoughts on the Bionx electric bike kit.
E+ Electric Bikes has conversion kit that houses the motor and battery in both the front and rear hubs of the bike. Interesting!
The eZee electric bike kit has been around for a while and uses a front hub motor. This is one of the more economical kits.
DaaHub electric bike kit is a new ebike kit from Wisper electric bikes. The unique part about this kit is that it is supposed to be easy to install on almost any bicycle. It is also designed to be easily removed if you want to ride your “normal” bike.
The E-Bike Kit offers a front or rear hub motor with options for lithium ion or lead acid batteries.
Currie Technologies (Izip, Ezip) offers an economical rear hub motor kit.
The BMC e-bike kit that uses a geared front hub motor for higher torque.
Want a kit with a lot of power? Check out the Crystalyte rear hub kits. Please note that some of their kits go above the US limit of 750 watts and 20 mph to still be considered a bicycle. High power kits will make your bike a moped and should abide by the laws of a moped. Oh and be careful 
Speaking of higher power here are the Phantom motors. See note above about high power kits.
Wilderness Energy offers a front hub motor kit.
Golden Motor offers front and rear hub motors. You can actually use their motors in both wheels if you want!
Amped Bikes has hub motors for front or rear hubs.
Hub kits only available on complete bikes:
The Shimano STEPS electric bike kit is a front hub motor kit from a long time bicycle component manufacturer who has a history of high quality bicycle components. This kit will be speced on complete ebikes only.
Mid Drive Electric Bike Kits
Mid drive motor kits allows the motor to power through the drivetrain or gears of the bicycle. This allows you to climb steep hills by using the electric assist in the lower gears of your bike.
EcoSpeed offers what looks like a very solid mid drive kit.
Stokemonkey electric bike kits are designed for the Xtracycle cargo kit in mind.
The Cyclone kit is an economical kit from Taiwan. Here is a link to their US site.
Mid drive kits only available on complete bikes:
The Bosch eBike System is an electric bike kit that locates the motor at the cranks of the bike which requires a special bike frame.
Friction Drive Electric Bike Kits
The Electric Bike Factory makes a kit that has a roller that rubs on the top of the bike tire to power the bike.

Excelent guide my friend, i helped me to decide what i will build !!!
Thanks Pavlos, I’m glad it is helpful!
Yes the Bionx kit is a nice system. I will be posting a review on it soon.
Can we expect reviews on the rest of these kits? Can you also make a note as to which kits are available for retrofit and which are only usable as original equipment only. Like all of the mid drive kits are pretty much OE only, and the stoke monkey is designed exclusively for the extra cycle/big dummy. If you want to put it on something else, there is no support. Maybe an article on the pros and cons of front vs rear hub drive. That’s all I got.
Electric motor bike is really very
innovative one.. these motorbikes stands for fuel efficiency which
comes with reduction of air and sound pollution. Electric motor bike
are true example of Eco friendly bikes. Indus India
Everyone is moving to electric motorbike and cars …one can say people are becoming environment conscious!!
Indeed, people are quite aware of environment and causious of their planet.
good luck when you need to order parts they refuse to order over phone then when you order over the net they send you an email 4 days latter that they want pics of item you call them and describe in detail they refuse order good luck staying in business stay away phone support is horrible
I love my AmpedBike conversion kit! I am a larger lady and use it for commuting and exercise. I did 17.65 miles today. I love the fact that I do not have to worry about wearing myself out or how I am going to get back if I go a long distance. Not to mention that it is good for the environment. A great way to to exercise and lose weight!
