All Kalkhoff bikes come with lots of extras: hub or motor powered front and rear lights, bells, fenders, chain guards and racks. Some include a built-in quick-lock or a rack-mounted pump. There are a number of features available for the discerning cyclist, whether it's the Magura hydraulic brakes, the B&M super-bright hub-powered headlight, the top-of-the-line Shimano internal hub or derailleurs or the three-layer powder-coated paint process.
But this bike isn’t just about the accessories. The powerful 48V 13Ah battery will allow you to pedal for longer, with some riders getting over 100 miles from one charge. The bike can be ridden as pedal-assist or throttle only and it’s equipped with full suspension and puncture-free Kenda tires. It folds up neatly to fit into the boot of a car or for commuting, though at 57 pounds, it’s heavy to cart around. A great value-for-money commuting bike with lots of features.
E-bikes are one of the latest ways technology is infiltrating the fitness market. Although they may seem techy and confusing at first, they really are just regular bicycles with a little extra boost. To test one, ask your local bike shop to demo a model they have available (pro tip: If a bike shop won't let you demo, don't shop there). Just getting on one will definitely help you understand how an e-bike works and how one might work for your lifestyle and goals.
“First, Taiwan and China have been building almost all the bikes for the entire world for the past 30-40 years. They have ecosystems and two generations of tradesmen that result in the best bikes in the world. Look at all the top brands—Giant, Specialized, Cannondale— they all make their top end bikes in China and Taiwan. Even look at the Italian brands and you’ll see they build their frames in China and Taiwan and paint them in Italy.”

In the 1890s, electric bicycles were documented within various U.S. patents. For example, on 31 December 1895, Ogden Bolton Jr. was granted U.S. Patent 552,271 for a battery-powered bicycle with "6-pole brush-and-commutator direct current (DC) hub motor mounted in the rear wheel". There were no gears and the motor could draw up to 100 amperes (A) from a 10-volt battery.[5]
Look at Bulls giving you options! Very similar bike, but with the Bosch Performance Speed motor. Why did I include if it’s so similar? Because I think Bulls has build super interesting commuters. They set you up with a adjustable stem so you can literally be as upright as you want, if you’re a posture freak. Underrated part of this bike: water bottle boss placement. Call me crazy, but it’s little touches like these that tip the scales on commuting bikes for me. It isn’t always easy to find places to put cages on e-bikes.

Torque sensors and power controls were developed in the late 1990s. For example, Takada Yutky of Japan filed a patent in 1997 for such a device. In 1992 Vector Services Limited offered and sold an e-bike dubbed Zike.[9] The bicycle included NiCd batteries that were built into a frame member and included an 850 g permanent-magnet motor. Despite the Zike, in 1992 hardly any commercial e-bikes were available.
We ran the C330 almost entirely in its speediest Turbo setting, switching back to Eco or Tour in heavy traffic for a more predictable assistance weaving between cars. Crucially, the display also displays how much assistance you’re getting as well as your speed, trip distance, etc. We used this to ease-back effort and stay in a light power sweet-spot, arriving at WIRED’s HQ without breaking a sweat.
As with all these bikes, the assisted speed is capped at 15mph, but unlike some of them, the Gtech eBike City or its identical (spec-wise) sibling the eBike Sport (this just has a standard frame rather than a step-through one) is light and agile enough for you to be able pedal harder without feeling like the weight is fighting you back down to 15mph. You can even, at a push, use it without the motor on flatter roads.

Having never ridden one before, I took a few electric bikes out to review in Central London and was an instant convert. For a commuter, they're ideal. While you still feel you've done exercise, the assistance means you won't arrive at work in a hot and sweaty state. The power boost whenever you start from a standing position is ideal for a speedy getaway at a traffic light with buses and lorries right behind you. And you'll get a nice ego boost every time you effortlessly ride past a struggling regular cyclist.
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.
