FRAME GEOMETRY  EcoBike electric bikes have been specially designed with the daily commuter in mind. The frame is constructed from a high-strength, lightweight 6061 aluminum alloy that maximizes safety and durability.  The enhanced frame design features comfort ergo-geometry that is more upright than a traditional mountain or road bike.  Every EcoBike electric bike is outfitted with suspension on both front forks (except Vatavio) and seat post to deliver a smoother ride. 

Prices have rarely been this low, with perhaps only the Xiaomi Himo electric bike that we covered costing less, at $261. Of course that e-bike is only available in China for now, unlike the Stark Drive Mini that can ship to the US, albeit for an extra $200 shipping fee. (Spoiler alert: I was able to procure a Xiaomi Himo via a friend in China, and assuming I can get it into the country, we’ll have that review coming up.)

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]
Probably the most important thing to consider when researching the best electric touring bike for you is how far you need your bike to take you every day. Be realistic about this. If you purchase a lower end electric bike, don’t be surprised when it only takes you half as far as you want to go. Think about whether or not there are going to be opportunities to charge your battery in the middle of your daily riding. If not, it might be a good idea to buy an extra battery.
To be honest, this bike is really designed for city commuters or kids riding around the suburbs. The fact that it’s foldable will let you carry it on the bus, on the train or even on the plane. It’s just not designed for heavy riding, long distances or tough terrains. If you want something sleek and fabulous at a fraction of the cost of most other e-bikes, this baby’s for you.
Having never ridden one before, I took a few electric bikes out to review in Central London and was an instant convert. For a commuter, they're ideal. While you still feel you've done exercise, the assistance means you won't arrive at work in a hot and sweaty state. The power boost whenever you start from a standing position is ideal for a speedy getaway at a traffic light with buses and lorries right behind you. And you'll get a nice ego boost every time you effortlessly ride past a struggling regular cyclist.
However, Emu sells a little foldable number if that's your bag. The Emu Crossbar is for  town commuters that require a sweet ride that's backed up by solid Shimano Nexus hub gears and Tektro brakes, which are adequate if not the best on the market. Riding is smooth and easy, with the crank moving sensor doing its best to iron out any gaps in power delivery.

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.
