Haibike ships the HardNine with 29-inch tires, 180-millimeter hydraulic disc brakes, a 100-millimeter front suspension fork, and a nine-speed Shimano shifting system. The bike’s LCD readout is affixed to the handlebars and displays the current speed, level of charge, remaining range, and current pedal assist mode. The company says the battery can be completely recharged in just four hours, minimizing downtime between rides.

When riding a normal bike through creek crossings, and rock gardens, I typically stop pedaling often to avoid pedal strikes, and to maneuver the bike. This approach is not compatible with the Turbo Levo’s weight. On it, continual pedaling was necessary, but the big tires and well-damped suspension enabled me to roll over obstacles I’d typically try to avoid, with the motor helping me power over them smoothly. To make this constant pedaling possible without pedal strikes, the bottom bracket is moved higher and Specialized has spec’d 170mm cranks that are a tad shorter than normal. 

Looking for electric mountain bikes? Propel has you covered. We carry many different types, most of which have a center drive motor since they perform best on the trail and they’re great for climbing. Our bikes have motor systems from leading manufacturers including, Bosch, Shimano, Brose and Yamaha. Most electric mountain bikes or EMTB’s are limited to 20 mph, but some do go up to 28 mph. We carry many different types listed by category below. We have full suspension, hardtail, fat tire, carbon fiber eMTB.
Your friends: We all have friends we wish wanted to pedal up hills with us. Many of who might be capable of leaving us in their dust on descents. These are young and old riders; riders lacking the fitness, time, motivation, or who just aren’t interested in climbing alone, at the back of the pack. You’ve done everything to get them back out riding with your regular crew, but pride and reluctance to hold the group back is keeping them away. 
On mine I got the Topeak front and SKS rear mud guards, an Axiom rear rack, front and rear lights. They didn’t have a headlamp with the lumens I wanted, so Tommy the owner went ahead and ordered one for me! He was always available for any question I may have had through his mobile phone, and updated me with pictures showing me different possible setups to see if I would like it.
The RideControl Evo display features a button control on the grip and a readout on the stem, giving you control over ride time, distance and cadence. Best of all, it gives you as very accurate percentage readout of how much battery is remaining, so no excuses for running out of juice! The five rides mode are Eco, Basic, Active, Sport and Power and there’s also a walk assist button.
The new Stumpjumper is the ultimate trail bike. Seriously, the damn thing rides like it’s on rails. It’s the most versatile trail bike we’ve ever made. And yeah, we’re stoked about that, but we’re even more excited about how well it’s tuned to you. We’ve said goodbye to proprietary bullshit, focused on your needs, and made, what we feel, is the new benchmark in trail bikes.
The Moterra is Cannondale’s biggest and baddest e-mtb and just looking at this thing you can see that it’s built to withstand some wicked downhills and big drops. With 130mm of front and rear travel, paired up with 27.5-inch wheels and trail-grabbing 2.8-inch tires, along with a KS LEV Integra Dropper Post make this pedal-assist mountain bike a great option if you want to climb farther to shred longer, but don’t want to lug your bike uphill for ages. The 250w motor, placed slightly farther forward than most other bikes to optimize weight distribution and handling, will give you a nice boost so you can enjoy the ride up and not be too gassed when you get to the top. After all, it’s all about the ride down, right?
The first functioning electric motor was displayed in the early 19th century, though the device constructed by British scientist Michael Faraday did little more than swirl a wire around a magnet when an electric charge was introduced. Still, the concept proved that electricity could do work. Functional electric motors would follow in many forms after that achievement in 1821. Soon scientists and tinkerers around the world, including visionaries such as Nikola Tesla, were experimenting with all manner of electric motors -- some worked with DC power, others with AC. By the end of the century, myriad electric motors had been produced, capable of exerting enough force with enough reliable control that they were practical for use in myriad applications.
Duke Eco-Marathon Team using an Electric Bike Technologies hub motor for the 2014 Shell Eco-marathon. The E-BikeKit motor provides optimal space saving because it does not require a chain (this makes it great for converting road bicycles to electric bicycles, which is what it is designed to do) but we hope to determine if it provides us with a better overall vehicle efficiency than our outboard motor.
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.
Countless others have popped up since all over the world, proving that the design has been popular with consumers. However, most people don’t know where the craze started. In fact, it can all be traced back right here to Coast Cycle’s original Buzzraw, which actually started life as Coast Cycles’ Ruckus bike. The Singapore-based company quickly changed the name to Buzzraw, probably fearing Honda’s lawyers.

There are various kinds and classifications of electric bikes on the market, but the more common type is the Class 1, or pedal assist, bikes which have motor units that are activated by pedaling and are limited to lower speeds. In the US, Class 1 electric bikes, the type tested and reviewed here, are limited to a top speed of 20 mph and their motors are designed with a speed governor to regulate this. These types of e-bikes resemble modern mountain bikes, but they have significant battery packs and small motor units integrated onto and into the frame design. The e-MTB pedal-assist motor is typically built around the bottom bracket and provides varying levels of pedaling "support" directly into the drivetrain while the cranks are turning. Most drive unit systems offer several support settings that provide pedal assistance between 25% and 100% of the user's pedaling input.


“People are buying electric bicycles as a way to reduce car trips,” Benjamin says. The data backs him up: 28 percent of survey respondents said they bought an e-bike specifically to replace driving a car. And many other reasons buyers listed for wanting an e-bike—including carrying cargo and kids, avoiding parking and traffic, and environmental concerns—also indicate a desire to get out from behind the wheel. Plus, you don’t need to change clothes or clean up when you arrive at your destination, because you don’t have to work up as much of a sweat.
If you really want to see the future take a look at the Fazua Evation, with a battery and motor this system weighs an incredible 4.7kg! The battery only has 250wh, but at 1.3kg you could easily carry a spare in a pack. The really interesting thing about this system though, is the motor and the battery can be removed from the frame, so you really do have two bikes in one.
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.
