Lightning Rods Big-Block mid drive kit

The original Lightning Rods kit was the most powerful mid drive available when we wrote about it back in December of 2014. But now, he has produced an even more powerful kit that he is calling his “big block”. It is wide enough that it fits between the pedals on extra-wide bottom brackets, like those found on some downhill bikes, the recently popular fatbikes, some cargobikes, and the Qulbix Raptor.     You can find our article on the original

Moped Rims and Tires for Hot Rod Hubmotors

If you want to rock a ton of amps in a hot-rod hubmotor street monster for the kind of sweet hard acceleration that can embarrass an expensive sports car, the latest trend is to mount the hubbie into a rear wheel that uses Moped rims and tires. This article will show you why you want this, and what parts are being used right now by garage builders to make this happen. ____________________________________________ Isn’t a moped just a light motorcycle?

MXUS 3000W V2, a Hot Rod Hubmotor

In early 2014, a few E-bike hot-rodders took a risk and bought a very large hubmotor direct from a Chinese company called MXUS, and the results were so good, this large hubmotor is now growing in popularity. For many years, the MXUS company has manufactured hubmotors for other companies to put their names on the sideplates, but…a couple of years ago, they began selling them under their own name. I mention this because the “MXUS” name may be new to

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

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. (edit: as of the spring of 2015, Lightning Rods now has his even MORE powerful “big block” mid drive, which can use twice as many amps as his basic kit, which is what is shown in this article) We bought the first two production kits before they were even produced. I say that up

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

10 Mid Drive Kits for DIY Electric Bikes

Some of the most refined electric bikes on the market are mid drives. And until recently, if you wanted a mid drive electric bike you were limited to buying an under-powered and overly-priced 250-watt Euro electric bike. Or…if you wanted a powerful bike, your only choices then were a $10,000 plus USA bike (like the Optibike or the Hanebrink). Recently, several notable mid drive kits have come onto the market which allows someone on a budget to build a mid

Cromotor, Monster Hubmotor for Electric Bikes

Zvonimir is an engineer who lives in Croatia, between Italy and Greece on the beautiful Adriatic Sea (ES member HAL9000V2.0). In a recent story, we told our readers how he developed the Greyborg Warp frame, so builders could have the option of an electric bike that was heavy-duty, and could also hold the largest possible battery volume. It is a big success with over 200 frames sold worldwide to date. But Zvonimir doesn’t just design things by using computers, he
