In a friction drive motor, a small, solid wheel rotates against the side of the tire in order to drive it. The first motorcycles used the same concept, with a motor mounted above the front wheel. The problem is that the drive rubs at the side of the tire. It's inefficient, and it quickly wears the sidewall away. Tires need to be replaced every couple hundred miles. For this reason, you'll seldom see electric bikes with this type of drive anymore.

Gearing: none (many hub motors, one motor revolution = one wheel revolution), fixed gear reduction for more torque, varies when geared motor drives the chain through the bicycle gears which increases torque about 50% (in low gear) for better hill-climbing and offers better top-end speed (in high gear) than direct drive systems using motors of similar wattage.

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.
Spec-wise, this thing is tricked out. You’ve got the option to go with  Suntour AION suspension or Fox Float suspension. The drivetrain is Shimano Deore XT. Same with the hydraulic disc brakes. The bike also comes with an ABUS Big Bordo folding lock that is keyed for both the batteries and the lock. Super convenient. There’s also loads of other options within the Delite line. Nuvinci and Rohloff drivetrains, 20mph and 28mph motors, standard and plus tires. You get the idea. Lot to choose from.
Cargo bikes and city bikes are common in the e-bike space, but until recently we haven’t seen that many performance road bikes. The Giant Road E+1 is a pedal-assist performance road bike that’s made for more than just commuting; the powerful motor can rank you up to 28mph very quickly on the highest setting so you can rip the flats, join your local group ride, or blast through the mountains with far less effort than a traditional road bike. Don't expect it to feel like a 16lb race bike when you lean it into high-speed turns, but the endurance-oriented geometry allows for an aggressive position on the bike and keeps the it nimble and agile at high speed.
At the end of the day, you'll have a ton of fun riding one. “There’s that nostalgic feeling that kicks in whenever you’re on one, that feeling you got when you started riding as a kid," LaLonde says. You might have to get on one to understand, but there are few things more smile-inducing than floating up a steep hill with little effort, Mary Poppins-style.
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.[43]
Simplicity powers the Gtech model, available in either a 20-inch “sports” crossbar frame or a 17-inch “city” step-through option. From using a carbon belt drive to a gearless system that allows a computer to adjust speed while pedaling, not only has Gtech streamlined the e-bike process, but they’ve also dropped the price to just north of $1,000. At a range of about 30 miles, this 35-pound bike offers a humble introduction to e-bikes.
If the bike is in fact similar to the EB-5, then it is probably a great around-the-city or campus electric bike, but perhaps not the best long distance commuter for rough roads. Though considering the bike won’t ship for at least another 4 months and the US shipping cost will bring the total price of the Spark Drive Mini to $499, impatient riders might be better off with the equally priced and Amazon-shipped EB-5 anyways.

The frame itself incorporates a series of mounts allowing you to easily trick-out the Road E+1 with a rack, fenders, or panniers to more aptly meet your touring requirements. Again, most touring purists will certainly scoff at the mere notion of pedal-assistance, however, individuals looking for more of a guided tour and less of a tour de force will swoon over the Road E+1.
Motor: We have a blog post showing some motor differences: https://www.ebikekit.com/blogs/news/its-whats-inside-your-motor-that-counts Cabling is probably the #1 issue when something goes wrong. Good connectors, good cables, and good assembly (bike shop!) are crucial Strain reliefs on all cable joints! Where you have a junction box or a connector, the stress is concentrated over a small area near this stiff spot on the cable. This can cause small breaks on the internal...
Electric Bike Conversion Kits are prepackaged sets of components designed to fit on a normal bike and convert it into an Electric Bike. These kits make it easier for end-users to find compatible, functioning parts and purchase them all together. A kit can range from a complete system that includes all the small parts you need, to DIY kits that include only a few parts and leave the rest up to the user.
In a friction drive motor, a small, solid wheel rotates against the side of the tire in order to drive it. The first motorcycles used the same concept, with a motor mounted above the front wheel. The problem is that the drive rubs at the side of the tire. It's inefficient, and it quickly wears the sidewall away. Tires need to be replaced every couple hundred miles. For this reason, you'll seldom see electric bikes with this type of drive anymore.
Electric bikes are here in a big way. Liberated from some of the normal constraints of standard bike design like weight and gearing, e-bike design has exploded; if you can imagine it, someone has built it. From cargo bikes to city bikes, messenger bikes to mountain bikes, road bikes, and even beach cruisers, there is something for everyone. The beauty of e-bikes is they make the joy of cycling accessible to so many people in so many ways.
