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.
Forward-thinking parents are giving up thier SUVs and opting for electric cargo bikes for getting the family around. Cargo bikes are seeing a resurgence in popularity with the rise of electric conversion systems that convert these awesome people movers into family toting electric vehicles. One year ago the Wall Street Journal ran a full page article in their weekend edition entitled The New Station Wagon. Since then the trend for...
The environmental effects involved in recharging the batteries can of course be reduced. The small size of the battery pack on an e-bike, relative to the larger pack used in an electric car, makes them very good candidates for charging via solar power or other renewable energy resources. Sanyo capitalized on this benefit when it set up "solar parking lots", in which e-bike riders can charge their vehicles while parked under photovoltaic panels.[66]
If you haven’t ridden or even seen a modern eMTB, here is what I have discovered. They are sturdy rigs that come standard with quality mountain bike components including beefy forks and rear suspension systems, strong disk brakes, and a reliable drivetrain. They are heavy but not that far out of the old downhill bike weight class. The distinguishing “e” features are the electric motor at the bottom bracket (some have hub motors), the battery pack, and the handlebar-mounted computer that controls the system. They have adjustable assist modes: off, low (barely helps), medium, and the battery-draining high mode. When everything is put together, they are something to behold.

Since the pedal assist doesn’t engage while coasting, climbing is where this bike really shines. We tested the bike on southern California’s fire roads, undulating traverses, and on some very steep, rocky, loose, and technical trails—the kind of stuff even the most skilled and fit riders would normally find themselves hiking up—and on the Turbo Levo we were able to ride all of it, and have a blast doing so. 
One of the biggest drawbacks to any ebike is its range — and perhaps to a larger extent, the capacity of its compatible battery. Since battery technology innovation is fairly stagnant, the German ebike company Riese and Muller decided that instead of making a bigger battery, it’d just slap a second one onto its latest release, the Delite nuvinci. Though the attachment does add more to the final price (to the tune of $823), it also increases the Delite nuvinci’s range to a whopping 130 miles — which is leaps and bounds further than any other ebike on this list.

Having a motor bolted to the bottom of a mountain bike that provides pedal assistance is an amazing leveller. The constant torque it applies to the chain rounds out the squarest of pedalling actions, which in turn helps stabilizes the rear suspension and counter pedal induced bob, seamlessly shifting your focus from pedalling efficiency to battery life.
The Brose motor puts out 250 watts nominally, and can peak up to a max of 460 watts. That’s around half what the 2016 Specialized Turbo S road bike we tested last year develops, but that bike’s much-larger motor sits in the rear hub, which would massively compromise performance on a full-suspension mountain bike like this one. Spend up to the Expert or S-Works spec Turbo Levo and you get a motor that can peak up to 530 watts. 
China has experienced an explosive growth of sales of non-assisted e-bikes including scooter type, with annual sales jumping from 56,000 units in 1998 to over 21 million in 2008,[72] and reaching an estimated fleet of 120 million e-bikes in early 2010.[2][73] This boom was triggered by Chinese local governments' efforts to restrict motorcycles in city centers to avoid traffic disruption and accidents. By late 2009 motorcycles are banned or restricted in over ninety major Chinese cities.[72] Users began replacing traditional bicycles and motorcycles and e-bike became an alternative to commuting by car.[2] Nevertheless, road safety concerns continue as around 2,500 e-bike related deaths were registered in 2007.[73] By late 2009 ten cities had also banned or imposed restrictions on e-bikes on the same grounds as motorcycles. Among these cities were Guangzhou, Shenzhen, Changsha, Foshan, Changzhou, and Dongguang.[72][73]
The first thing many cyclists do when checking out a new bike is give it a lift to gauge the weight. You’re in for a little scale shock if you try that with an e-bike. The battery, motor, extra components, and reinforced frame make e-bikes inherently heavier than standard bikes—to the tune of about 20 pounds. Modern geometry and engineering help them handle well despite their weight, and obviously the motor-assist makes the extra pounds disappear when you start to pedal. But you’ll need more muscle to get them on your car rack or up and down stairs.
E-bikes are classed according to the power that their electric motor can deliver and the control system, i.e., when and how the power from the motor is applied. Also the classification of e-bikes is complicated as much of the definition is due to legal reasons of what constitutes a bicycle and what constitutes a moped or motorcycle. As such, the classification of these e-bikes varies greatly across countries and local jurisdictions.
