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.
On the road, it takes only a few turns of the pedals to activate the Vado’s motor and get it up to speed. In Turbo mode — the bike’s highest level of pedal-assist — the Vado reaches speeds of up to 28 miles per hour, after which the electric drive system automatically shuts off to conserve power (and abide by local law). A built-in LED readout on the handlebars allows riders to monitor battery life, check current speed, and track calories burned while also being able to glance at distance traveled. The Turbo Vado Mission Control app (iOS/Android) also connects to the bike via Bluetooth and allows riders to further tune their ride and adjust the bike’s settings.
Designed for the same maneuverability as a non-electric bike, this roughly $3,000 model designed for the city can handle hills and distance. Using a Bosch motor for 100-mile cycling on flat or hilly terrain and a lightweight aluminum frame, the Dutch-made Gazelle model aims for a “sporty posture” and “precise cycling performance” in a robust offering.
In a parallel hybrid motorized bicycle, such as the aforementioned 1897 invention by Hosea W. Libbey, human and motor inputs are mechanically coupled either in the bottom bracket, the rear wheel, or the front wheel, whereas in a (mechanical) series hybrid cycle, the human and motor inputs are coupled through differential gearing. In an (electronic) series hybrid cycle, human power is converted into electricity and is fed directly into the motor and mostly additional electricity is supplied from a battery.
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.
