Controllers for brushless motors: E-bikes require high initial torque and therefore models that use brushless motors typically have Hall sensor commutation for speed and angle measurement. An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and thermal protection. Bikes with a pedal assist function typically have a disc on the crank shaft featuring a ring of magnets coupled with a Hall sensor giving rise to a series of pulses, the frequency of which is proportional to pedaling speed. The controller uses pulse width modulation to regulate the power to the motor. Sometimes support is provided for regenerative braking but infrequent braking and the low mass of bicycles limits recovered energy. An implementation is described in an application note for a 200 W, 24 V Brushless DC (BLDC) motor.
The Liv Amiti-E+2 is a low-priced but highly versatile e-bike. It’s just as much at home on the pavement as it is on bike paths and rail trails. But don't feel constrained to groomed paths. Front suspension and 42mm-wide tires mean you can take on off-road detour on your way home from work. Speaking of work, this e-bike makes a great commuter thanks to rack and fender mounts and integrated lights for riding after dark. Internal cable routing and a nicely integrated battery make for clean lines and 9-speed shifters give you plenty of gearing options for whichever type of terrain you decide to tackle. This do-everything bike is great option if you’re riding includes a little bit of this and a little bit of that.
E-bikes use rechargeable batteries and the lighter ones can travel up to 25 to 32 km/h (16 to 20 mph), depending on local laws, while the more high-powered varieties can often do in excess of 45 km/h (28 mph). In some markets, such as Germany as of 2013, they are gaining in popularity and taking some market share away from conventional bicycles, while in others, such as China as of 2010, they are replacing fossil fuel-powered mopeds and small motorcycles.
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.
Motorcycle manufacturer KTM has long produced bicycles too, but it is in the e-MTB category that the brand’s heritage is really employed. Motocross fans and riders looking to get into e-MTB riding will appreciate KTM’s decision to use a ‘precise’ 29er front wheel and ‘traction rich’ 27.5-Plus rear wheel (MX bikes also feature different front/rear wheel sizing), an approach some other manufacturers have also adopted (e.g. Canyon). The bike is adorned with a solid build kit including e-MTB-specific parts like SRAM’s EX1 drivetrain.

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.
Update: I've had the bike about 4 months now and ride it almost everyday, it is my primary form of transportation, and I have been pleased with it's overall performance, the battery is holding up pretty well and I've never not made it home without juice to spare, the only issue I've had is with flat tires so I wanted to highly recommend putting green slime in the tires, you do not want to have to deal with getting the back tire off for a flat, but other than that the bike is running great, as others have said it is a little less powerful than you may expect but I am very satisfied with the build quality and quality of components. For saddle bags I got the type of bracket that wraps around the seat post and saddle bags meant for that kind of bracket and they have worked well for me, so I can carry my shopping and groceries easily on the bike now . http://www.amazon.com/gp/product/B0030RS5CA?redirect=true&ref_=cm_cr_ryp_prd_ttl_sol_18 http://www.amazon.com/gp/product/B00K6CEPGM?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s01
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.

When you are one of the top car manufacturers in the world witnessing an ever-changing landscape of reluctant buyers, what should you do? Ideally, you take scope of what works and phase out what doesn’t. GM’s bold Bolt plan was to offer the electric vehicle (EV) as a personal means of transportation and a shared mobility platform through its Maven program. We haven’t heard much from that initiative and it seems GM is ready to get in bed with the top two ride-hailing companies, Uber and Lyft. Is GM a bit lost in its strategy? Or is it figuring out what works and sharpening its vision?
The Haibike AllMtn line makes an appearance again with this incredible price-point option. The AllMtn 6.0 is a nice option with entry level components but the same aggressive build as the rest of the AllMtn line. And when I say entry level components, I definitely don’t mean that as a negative. You still get 150mm of travel with a Suntour Aion 35 RC suspension fork, a RockShox Deluxe RT rear shock, Magura MT32 hydraulic disc brakes, and Shimano Deore M6000 drivetrain with 20-speeds.
The original Power Plus model was one of the most popular in its class, introducing the joy and practicalities of e-bikes to a huge audience around the world.

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.
