A Kalkhoff Pedelec is a lot more than simply bolting a motor onto a great bike. Their electric-assist bicycles utilize a brushless DC motor system that is lightweight, precisely-controlled, efficient, low-maintenance, and reliable. The Panasonic drive system is center drive, meaning that it's designed to be in the middle of the bike for a low center of gravity, stability and an easy integration with the drivetrain. The drive unit is more than just a motor; it also has a torque sensor and controller unit as well - all in the weatherproof casing, surrounding the motor. The torque sensor and the controller senses how hard you're pedaling and adjusts how much assistance the motor gives you through the drive sprocket.
This bike is designed for hauling. The Yuba Spicy Curry has a combined capacity of 500lbs (200lbs on the front including rider, and 300lbs of passengers or cargo on the back). To help move this weight, you’d expect a decent motor, and the Bosch Performance Line CX delivers. Normally only found on mountain bikes, the 75Nm of torque makes light work of hills, even with the heavy load.
From the tropics to the polar caps, Stark Drive is designed to handle a broad range of temperature conditions with a ruggedized frame and high quality battery pack as well as all terrain tires (standard) or even our fat tire model. Take Stark Drive with you wherever you go. When Designing Stark Drive in Stockholm Sweden we were very conscious of the fact that weather effects battery life on your electric bike so we designed our electric bike with this in mind.
“At $500 apiece,” he says, “the company would be selling e-bikes at a loss, once they factored in product liability insurance, quality control, regulatory compliance, safety testing, and post-sales service and support. Chinese e-bikes could certainly ‘leak’ into the U.S. market near that cost, be sold as a loss leader, or be marketed directly on eBay, but a fully costed business model could potentially lose up to $250 per bike.”
E-bikes are zero-emissions vehicles, as they emit no combustion by-products. However, the environmental effects of electricity generation and power distribution and of manufacturing and disposing of (limited life) high storage density batteries must be taken into account. Even with these issues considered, e-bikes are claimed to have a significantly lower environmental impact than conventional automobiles, and are generally seen as environmentally desirable in an urban environment.[65]
The downside to this mountain-bike build and specification is obviously the weight, at 24.5kg the Trekking feels heavier than the other bikes on test, and rightly bills itself as suitable for heavier riders, too. As with the other bikes here, this is only really a problem for smaller riders, or riders needing to take the bike up or down steps regularly. With its bomb-proof build, full guards and heavy-duty rack, the Haibike is the perfect choice for a burly rider or for doomsday preppers, ready to out ride the apocalypse.

For an overview of Stark Drive Electric Bike, its features and our story click above. Our passion for biking and our determination to take electric bikes mainstream have driven us to create the world’s most affordable electric bike. As technology improves, so will Stark Drive with the caveat that we will always offer the most affordable electric bikes in the world.

Upper Dublin Township in Pennsylvania is initiating a pilot project to gauge the advantages of using electric bicycles. The e-bike, as they are more commonly known, will be used for police work and for the Township’s Sitewatch program, which patrols and monitors parkland and playing fields. The people behind the program believe the electric bike could prove to be a useful tool, giving police officers and parks personnel a clean,...

E-bikes mostly use motors and battery options from a few major suppliers: Bosch, Yamaha, Shimano, and Brose. A few other brands exist, but are less reliable or powerful. Some, like the Yamaha system, have more torque and others are quieter. But generally all four make good options. Look for motor output (in watts) which will give you an idea of total power. But watt hours (Wh) is perhaps a better figure to use—it takes into account battery output and life to give a truer reflection of power.
