Ebike Wiring…Defining the Rats-Nest

Editor note: Part 2 of a 4 part series on the wiring of DIY ebikes Make no mistake about it…there is no great deal of expertise in building a drive system for an electric bike. It is not rocket science….it is not even as hard as tuning a car science. DIY ebikes have an array of wires that can quickly and often times turn into a rats-nest if the builder is not thoughtful. Wires are a messy problem. Where as the

The 3 Critical Components: Motor, Controller, and Battery

Hot-rodding an ebike is not as simple as some people might think. That is because you need to consider three critical interlinked components when hot-rodding, and if you don’t change all three components, your ebike probably won’t go any faster, and in fact might go slower or roast something. Think of it as the electric bike bottle neck…if one of your components can’t hold up to the  extra power?…you’re not going anywhere faster, and…you might end up in the embarrassing

A Home-Built Ebike Battery Pack from 18650 Cells

Editor Note: Affordable and powerful 18650 battery cells are the hottest thing in the DIY electric bike revolution (most well-known from their use in cordless tools). Bike builders everywhere are discovering that clustering many 18650s together are an effective way to build not only an affordable pack, but one with unbeatable performance and safety. Note that even though they are safer than soft pouch LiPos (popular with RC enthusiasts), it is still a lithium chemistry, which is always dangerous when

Lightning Rods 2800W mid drive kit

  This is the most powerful production mid drive kit that you can run through the bikes gears, and the big surprise is how quiet it is.

12 E-bike KIT power levels, from 360W to 8,000W

If you are fairly new to the idea of an E-bike, and you think you might want one, this article hopes to give you some info to help you get some kind of an idea about what type of kit will fit your needs. Factory E-bikes are very expensive compared to the kits that you can get and install on your own bike, but…some people don’t mind paying more to get good customer service from a local dealer, and getting

High Current Batteries that are NOT LiPo

High performance requires high amps, but LiPo batteries can be dangerous for someone who is inexperienced with them. LiPo is capable of putting out VERY high current (the C-rate), and if you are building a racing E-bike, they are simply the best choice. A LiPo pack will be smaller, lighter, and will put out more peak and continuous amps than any other pack you can buy. The problem is that…for E-bikers who want something that is much safer, but has better performance

DIY Mid drive builds, the why and the how, part-2

The reasons why someone would want a non-hub build…in spite of the complexity, noisy drive components, and extra cost…was discussed in Part-1. Here, in Part-2…you have decided that you want a non-hub drive system, and you want to know what components others have used with some record of success. The two systems I’ll describe here are…first: a VERY high powered “one-speed” system that drives the left side of the rear wheel (leaving the stock right-side pedal-drive system just as you
