With almost as many awards as technical features, it’s no secret why we opted to include HaiBike’s SDURO HardNice 4.0 in the list. First and foremost, this sleek aerodynamic ride doesn’t even initially come off as an electric mountain bike. That is until you experience first-hand the integrated Yamaha PW Drive Unit offering dynamic support and a top speed of 20 mph. Also, the bike features a shock-resistant skid plate that works to protect the motor from harm, and a Yamaha LED display that’s small yet robust and works to keep you informed on the bike’s status and functionality.
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.
By 1898 a rear-wheel drive electric bicycle, which used a driving belt along the outside edge of the wheel, was patented by Mathew J. Steffens. Also, the 1899 U.S. Patent 627,066 by John Schnepf depicted a rear-wheel friction “roller-wheel” style drive electric bicycle. Schnepf's invention was later re-examined and expanded in 1969 by G.A. Wood Jr. with his U.S. Patent 3,431,994. Wood’s device used 4 fractional horsepower motors; connected through a series of gears.
Not the best bike but good for what it is. 250watt. not enough power even for small hills on its own and does not do 15/hr even on flat ground. battery looses power when cold but still works. Over all so far, dispite the above I give it 4 stars because it is what you would excpect in a cheap bike and it does work. There is no braket for the headlight tho so be warned you will have to improvise on that.
This article first appeared in Electric Bike Report in June of 2013. Since then, we’ve made some changes to our motor selection - our Direct-Drive motors are now all High-Torque 6x9 wound, so they run slower (approximately 15mph at 36v or 20mph at 48v), and our Geared Motors have been replaced by a 500w version, (approximately 20mph at 36v or 28mph at 48v). The Direct-Drive is now our Heavy-Duty motor and the...
A 2008 market survey showed that the average distance traveled in the Netherlands by commuters on a standard bicycle is 6.3 kilometres (3.9 mi) while with an e-bike this distance increases to 9.8 kilometres (6.1 mi). This survey also showed that e-bike ownership is particularly popular among people aged 65 and over, but limited among commuters. The e-bike is used in particular for recreational bicycle trips, shopping and errands.
Mountain bikers and their associations (which I used to be a proud member of), should reconsider their anti-eMTB stance, realize there is a need and demand for Type 1 eMTBs, and focus their efforts on keeping trails open for all mountain bikes. Mountain bikers deserve the right to ride more of our public trails than we are currently allowed. I won’t open a can of worms with my strong opinions on where I believe mountain bikes should be allowed, but suffice it to say that we don’t have near enough access as we should.
All models of the Turbo Levo use a frame made from M5 aluminum alloy, with the motor and removable battery integrated inside. The frame and fork use 148mm (rear) and 110mm (front) spacing. Specialized 6Fattie Purgatory (front) and Ground Control (rear) 3-inch wide tires are laced to 38mm Roval Traverse rims. Rear stays and pivots are beefed up to handle the additional weight (48.5 lbs) and torque, and bridges are added to the stays, over the non-motorized Stumpjumper. The front fork is a RockShox Yari XC with a 15mm thru-axle. The 135mm rear travel is provided by a custom Fox Float Performance DPS shock with automatic sag adjust.
This bike is named the GSD because with it you can Get Stuff Done. Twenty-inch wheels keep the center of gravity low so heavy payloads—it's rated up to 400lbs—are easy to balance and a short (for a cargo bike) 70-inch wheelbase, similar to a standard single bike, make the GSD easy to maneuver. Designed with the urban commuter in mind, the bike can easily break down to 60 percent of its original size to fit into the back of a car and the rear rack doubles as a stand that allows it to stand upright to minimize space inside tight apartments. Put two child seats on the back and take the family along, or drop the seat and let you kid take the bike out himself—anyone from 4'10" to 6'5" can ride this bike. Last but not least, the GSD gives you the option of adding a second battery to extend your range up to about 150 miles on a single charge.
