Generally the most common conversions use a hardtail mountainbike with disc brakes and 26" wheels. Preferably a diamond frame with room in the center for mounting a triangle battery bag or hardshell battery pack. Kit installation is usually simple, and local bike shops are sometimes happy to do the work if you contact them about it.

Hub motors are sold as either geared or direct drive: Geared hubs are preferred for hill climbing ability and zero drag when coasting, while DD hubs are more durable and suitable for high speed. Extreme hill climbing and high torque applications (fatbikes, hauling cargo, popping wheelies) usually requires a mid drive, which is covered in the motor section below. Ebike battery packs from the listed suppliers are generally compatible with kits from any supplier, at worst you may need a different connector, which can be easily replaced. You probably want a battery pack that is 36, 48, or 52 volts, depending on whether you prefer lower price and longer range or a higher topspeed. DIY lipo battery packs can be built cheaply but doing so can be a fire hazard so actual packs are recommended. All hub motors above 24 V should be installed with torque arms for safety.

Faster e-bikes usually run at higher voltage. But higher voltage reduces range as well, because lower speeds are more efficient. So e-bikes running higher voltage will have less range unless significantly more battery capacity is added to compensate. This causes higher speed builds to be increasingly expensive for the same range that could be gotten from a slower e-bike. Therefore deciding on a build requires balancing several factors: Range, Speed, Cost, and Quality. Voltage

These are nonessential common modifications to help with comfort and long term durability. Some options like Slime will slow the bike somewhat (increased rolling resistance) but this is less of a concern when you have an electric motor compared to a regular bike.

These lists show supplier location as well as some of the products they are known for. Keep in mind that internationally shipped battery packs often have very high shipping costs. Many overseas vendors are quite good but it can also be expensive to do returns/replacement/warranty stuff, so bear that in mind. Site

Run by the great folks at electricbike.com, stocks batteries, battery bags, kits including the Magic Pie 5, BBSHD, Cyclone high power mid drive, connectors, lights, custom built ebikes and accessories. Cheapest US supplier for battery packs.

Posting guidelines for wiki: For suppliers to be marked "Trusted" they must have a good amount of positive feedback from the community. If adding a supplier to this list you may be requested to provide proof of feedback, so if in doubt add the link to the Full List instead. to have content added to this wiki please message the moderators.

While we would love if you bought from us there are a lot of good companies in the documentation and we hope it helps you to make the most informed choices for your build. Intro to e-bike kits

* Bikes with rim brakes should be upgraded. This may include Kool Stop Salmon brake pads or trying to retrofit the bike for disc brakes using an adapter. Example adapters [are here](http://www.amazon.com/brake-bracket-frame-adaptor-bicycle/dp/B00HFWAMEA), and [here.](http://www.amazon.com/dp/B003QREO1A)
