E-bikes are zero-emissions vehicles, as they emit no combustion by-products. However, the environmental effects of electricity generation and power distribution and of manufacturing and disposing of (limited life) high storage density batteries must be taken into account. Even with these issues considered, e-bikes are claimed to have a significantly lower environmental impact than conventional automobiles, and are generally seen as environmentally desirable in an urban environment.[65]
The sub has been awesome in giving me confidence, I got a Giant XTC from CL. and was going to order all the parts from Luna's Black Friday Sale. A couple of questions, I will have a bike shop remove the bottom bracket, but I am assuming the Bafang 750 with the 17 AH battery should be an easy install at that point (or is it)? I am thinking of having the bike shop install the motor too and I do the the rest. besides a pedal crank, Allen wrenches etc, what tools will I need? Any top rated videos to watch? Is the speed sensor worth it? What about the half twist vs. full twist vs thumb throttle? Color display,, etc. Since the bike has a 10-speed cassette, will that be good or bad (me thinks good). Any other thoughts or pointers? Should I order the stuff from Aliexpress or Ebay?
Focus manage to offer both one of the lightest all-mountain capable e-MTBs and also one of the greatest battery ranges. How do they do it? Simple. A smaller-than-most, 378Wh battery is integrated into the frame (the other bikes in this list feature a battery around 500Wh). Another, optional, 378Wh battery also attaches externally within the mainframe. It’s a novel idea, and the bike is noticeably more playful than some others in its lightweight guise. 

A carbon frame shaves off several hundred grams of weight, of course. However, this is largely irrelevant when it comes to eMTBing. The two major advantages of carbon on eMTBs are, on the one hand, greater freedom in optimising the frame design and, on the other hand, increased stiffness. Thanks to carbon, smooth transitions can be achieved, better facilitating the integration of motor and battery. Unfortunately, the magical black material also has a few potential disadvantages. Carbon has poorer thermal conductivity, which means that heat is dissipated less efficiently with a fully integrated motor, and stiffer is not necessarily always better. Frames and wheels require a certain amount of flex to be comfortable and to generate enough traction through curves. Buying a carbon eMTB can currently only be justified by aesthetics rather than functionality.


It’s probable that GM was hoping for more press for its announcement of the same day as Musk’s interview going live, that it had actually built and was going to sell a pair of electric bikes. It launched a $10,000 naming contest. The bikes were built in-house by GM, including engineers who had worked on the Bolt. The Director of General Motors Urban Mobility Solutions, Hannah Parish said:

Introducing a fully integrated, electric-assist mountain bike that takes our Altitude’s legendary handling and ride quality and adds a compact, powerful drive system. The new Powerplay™ drive system was designed in parallel with the frame, delivering ultra-short chainstays, optimised suspension kinematics, super-low centre of gravity, and class-leading torque. The result is an e-MTB that actually rides like a proper mountain bike—perfect for everything from self-shuttling all mountain trails, finding flow between the descents, and squeezing in power lunch rides. 
Automated Transit Networks (ATN), and the small-vehicle subset of Personal Rapid Transit (PRT), are emerging technologies that can help solve the related problems of congestion, dependence on foreign oil, and planetary climate disruption. ATN/PRT offers clean, quiet, responsive public transit with automated non-stop service available 24 hours a day. In addition to these service benefits, PRT costs far less to build and operate than other transit options ¯ and is safer than walking and cycling on nearby busy streets.
Folding Electric Bikes- These are mostly used when people need to combine different modes of transport. For example, if you need first to take the train or bus, a folding e-bike can be useful to carry along. Also, very short trips are more convenient with these electric bikes, since you don’t need to bother tying them up. Typically, these are very light, even with the motor and battery. At Christmastime, consider this model for urban friends and family who use mass transit to get around.

Shell Eco-Marathon Americas Competition 2014 1st and 2nd Place Winners Both Used an Electric Bike Technologies Hub Motor! The Mater Dei Supermileage Team of Mater Dei High School, in Evansville, Ind., took the top spot in the Prototype category. The team built a vehicle using an electric bike motor from Electric Bike Technologies USA and won the electric plug in class at the 2012 Shell Eco Marathon Americas.  They raised the...

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.

“Rather than bolt on a bulky off-the-shelf system, we struck out on our own to redefine the category. The Powerplay system is the result of designing an electric drive for the suspension and geometry needs of proper mountain bikes; in fact, the geometry and pivot points of the Altitude Powerplay are identical to those of the new Altitude. In our opinion this is the first electric bike that actually rides like a mountain bike should.”
Fast and fun on the trail, the SDURO HardNine handles rough terrain with ease, while its large tires roll over most obstacles without missing a beat. The pedal assist makes for quick, energy-saving climbing and the bike descends surprisingly well, too. Its front suspension provides a nice level of cushion on bumpy trails and while we missed having a full-suspension on this model, that would have added additional weight and costs.
Cyclocross demands a lot from both bike and rider, and the CruX has been engineered to give the precise and efficient performance needed to win races, and the durability to win them every weekend. The frame's geometry and character has been created with input from some of the world's most accomplished racers, making for an agile, easy-to-shoulder bike that is as fun to ride in a World Cup as it is in the local woods.
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.
TerraTrikes make great electric recumbent trikes. Here are a few how to tips for converting the Rover and Rambler models, specifically with internally geared hubs. The TerraTrike Rover and the rambler models both are offered with internally geared hubs. It is possible to convert the trike to external gearing, but you will probably want the help of a bike shop that is familiar with recumbents. For a good bike shop,...
Riding position: You also may wish to check out an e-bike’s riding position before investing in it. For short trips, the riding position might not make much difference, but for long journeys, the upright "Dutch" style with pulled-back handlebars is very comfortable – particularly for tall riders. The same goes for mountain bike styles, though these bikes are not often designed to actually go off-road.
Another type of electric assist motor, often referred to as the mid-drive system, is increasing in popularity. With this system, the electric motor is not built into the wheel but is usually mounted near (often under) the bottom bracket shell. In more typical configurations, a cog or wheel on the motor drives a belt or chain that engages with a pulley or sprocket fixed to one of the arms of the bicycle's crankset. Thus the propulsion is provided at the pedals rather than at the wheel, being eventually applied to the wheel via the bicycle's standard drive train.
