Because the power is applied through the chain and sprocket, power is typically limited to around 250–500 watts to protect against fast wear on the drivetrain. An electric mid-drive combined with an internal gear hub at the back hub may require care due to the lack of a clutch mechanism to soften the shock to the gears at the moment of re-engagement. A continuously variable transmission or a fully automatic internal gear hub may reduce the shocks due to the viscosity of oils used for liquid coupling instead of the mechanical couplings of the conventional internal gear hubs.
E-bikes use rechargeable batteries, electric motors and some form of control. Battery systems in use include sealed lead-acid (SLA), nickel-cadmium (NiCad), nickel-metal hydride (NiMH) or lithium-ion polymer (Li-ion). Batteries vary according to the voltage, total charge capacity (amp hours), weight, the number of charging cycles before performance degrades, and ability to handle over-voltage charging conditions. The energy costs of operating e-bikes are small, but there can be considerable battery replacement costs. The lifespan of a battery pack varies depending on the type of usage. Shallow discharge/recharge cycles will help extend the overall battery life.
E-enduro bikes aren’t as different to regular bikes as one might imagine. All of the fundamentals are the same and by nailing the geometry and sizing Vitus has produced an amazing e-bike with the E-Sommet VR.Sure there are a couple of little things we’d probably change, like the STEPS Di2 mode shifter and rear tyre, but that’s about it. And given how much cheaper the Vitus is compared to the competition, you can easily afford to make these changes and even buy a spare battery. The E-Sommet VR is no golf buggy, but Vitus has it’s certainly hit a hole in one with this bike.
The Super Commuter is very aptly named. The 350w Bosch motor will help you sustain speeds of up to 28mph, and the burly, 2.4-inch wide, Schwalbe Super Moto-X 650b tires will keep you secure on even the roughest city streets, and Shimano Deore hydraulic brakes provide ample stopping power. Fenders provide welcome protection from road spray so you arrive at your destination fresh, integrated lights are critical for post-sunset riding, and a side-view mirror hanging on the left side of the handlebar gives a great view of traffic around you. After all, you can ride at the speed of urban traffic on the Super Commuter.
You can’t really get a cheap e-bike just yet. But if you keep the car in the garage more often, you’ll save cash on maintenance and gas money. Not to mention the added health benefits and potentially fewer sick days from getting more exercise. Prices vary widely, but you should expect to pay at least $1,500 for a decent e-bike, and considerably more ($2,500-$5,500) for a quality bike with a motor system from a major manufacturer like Bosch, Shimano, or Yamaha.
If you’re looking for even more performance and an even more refined bike, you’ll find what you’re looking for at Specialized. Their bike embodies the company slogan “Innovate or die” in a perfect way and is full of smart solutions. Many of them, such as the specially developed app for tuning the motor, the integration of the battery, and the small remote lever for selecting the support level, are obvious. Some, on the other hand, only become clear when you take a closer look – such as the Autosag valve on the shock for a simplified setup process, or the omission of a spoke magnet. The Levo also won us over with its outstanding riding characteristics, obviously. It rides comfortably, climbs quickly and efficiently, and has exactly the right mix of agility and stability. It’s the ultimate machine that promises to bring a huge smile to every rider’s face after just a few metres on board – no matter whether beginner or a pro. The Specialized Turbo Levo S-Works Carbon is currently the eMTB offering the best overall package, and thus the deserved Best in Test! The best eMTB of the 2018 season!
The need to develop a high-performance e mountain bike provoked the launch of the ATOM X project over three years ago. A team of experts was put together from the fields of MTB geometry, suspension and performance, advanced motor, battery and IT technologies. That is how the innovative and patented “X System” came about, which represented an integration that was both ergonomic and different. It was developed until it became the best eMTB with the best of both worlds: high performance and the most advanced electric technology. See the ATOM X e mountain bikes...
Depending on local laws, many e-bikes (e.g., pedelecs) are legally classified as bicycles rather than mopeds or motorcycles. This exempts them from the more stringent laws regarding the certification and operation of more powerful two-wheelers which are often classed as electric motorcycles. E-bikes can also be defined separately and treated under distinct Electric bicycle laws.
