2014 eZip Trailz Commuter, $750 with Lithium battery

The eZip Trailz has been a perennial survivor at the bottom of the lists of factory E-bike models for sale to the public for years, due to their low price. I haven’t been a fan of them…until now. Just to be clear, they didn’t suddenly improve the quality of an “entry level” E-bike…the bicycle part of this model is still the same as it was before (steel frame, no disc brakes, etc). Without the electrical kit, this bike is typical for the

Qulbix Raptor 140, slimmer with a bigger battery

The Qulbix Raptor has a devoted following as an off-road E-bike that will fit any one of the large and powerful rear hubs that are popular. The large stock battery space of the Raptor frame box is 160mm wide. This is the widest frame space for the battery that is available, and it allows LiPo packs to be mounted sideways. Our original article on the Raptor can be found here. Some builders wanted a Raptor that was just a little

2-speed hub motors, E-matic and Xiongda

This is an important development for E-bikes, but they have not yet evolved into their final form. These are relevant because hub motors remain the simplest, easiest, and most affordable way to electrify a bicycle. When we have discussed electric kits that can be affordably added to a bicycle, they generally fall into three categories. Direct-Drive (for silence, or high-performance), geared hubs (for general efficiency and stealth), or non-hub (for street-legal low power limits, or extra steep hill-climbing). A 2-speed

Pininfarina Fuoriserie, A stylish Italian E-bike

At first glance, this is just a stylish and simple E-bike with a rear hub. However, the exciting part is…who designed it. Pininfarina is the design studio that is most well-known for creating the shapes of some of the most famous exotic cars in history. Not only did Pininfarina design these rolling works of art, these iconic automobiles influenced an entire generation of car designers. I will point out only a few, and include popular culture references about them to

Aldi stores carry Generic Bike with Bafang mid-drive

Aldi is an unusual store. They are based in Germany and they are primarily a grocery store that is expanding into many countries. I was only recently introduced to the Aldi brand when a store was built in my home town in north-eastern Kansas. It was only when I began researching for this story that I found out the Aldi brand was once one store chain, started by two German brothers, Karl and Theo Albrecht. There was a business disagreement,

Yamaha YPJ-01, a light mid-drive road bike

Yamaha was one of the early adopters of electric bikes. In fact, they invented the term “PAS” in 1993, which stands for Pedal Assist System. This is where the rider doesn’t use a hand-throttle, but by simply pedaling with your feet, the bike will add some power. Depending on the level of power-assist you dial-in, you can be going very fast with almost no physical strain.     PAS systems are not only popular in many parts of the world,

Boston Police using electric bikes for the marathon

The Boston Police department has been seen using electric bikes during the 2014 Boston marathon, which was held just a couple of days ago. The TV news video (ABC station affiliate WCVB) had very little information about the specifics of the bike, and only mentioned that the two biggest benefits were the added speed and endurance that it provided officers in crowds, and also that the integrated loudspeaker/siren was very useful for officers when addressing crowds. This particular model (currently called the “Vbike”) was assembled

Qulbix Raptor, Offroad Hot Rod Electric Bike

The Qulbix Raptor is a high-performance E-bike frame that is made to allow a very large battery pack, and a very high-powered rear hub-motor. We’ve been wanting to write about the Raptor for some time, and since they just recently changed their company name from Torque to Qulbix, that makes this month a good time to finally delve into the details. Note: the “Qulbix” name was developed to have something that is very different than any other name out there.

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
