The environmental effects involved in recharging the batteries can of course be reduced. The small size of the battery pack on an e-bike, relative to the larger pack used in an electric car, makes them very good candidates for charging via solar power or other renewable energy resources. Sanyo capitalized on this benefit when it set up “solar parking lots,” in which e-bike riders can charge their vehicles while parked under photovoltaic panels.
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…

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.
Foldability: Not all folding e-bikes are small. Some full-size electric bikes with standard 26-inch or 27.5-inch wheels can be folded to fit into compact spaces. Make sure you’re aware of a folding bike’s weight before you buy it, though. “Foldable” doesn’t always mean light.
The eBike Store is Portland’s first all-electric bike shop. Founded in 2008 by owner, Wake Gregg, The eBike Store provides a wide selection of electric bicycles from an array of top brands, in a comfortable and supportive retail environment.
If you cannot find the bike you’re interested in here, please contact me and I’ll do my best to track it down, shoot some videos and add it! New videos are regularly added to my YouTube Channel here. Have fun and ride safe 😀
The term “pedelec” (from pedal electric cycle) refers to an e-bike where the pedal-assist electric drive system is limited to a decent but not excessive top speed, and where its motor is relatively low-powered. Pedelecs are legally classed as bicycles rather than low-powered motorcycles or mopeds.

Power assist bikes typically use an electric motor and on-board electric battery to add propulsion to the traditional pedal-and-chain system. The power can be turned on or off, and dialed low to high, depending on how much energy the rider desires to use.
Go big or go home with the Yuba Spicy Curry. This is the largest of the e-bikes we’ve amassed in this collection, and it’s for the serious commuter or the person who does all of his or her shopping by bike. Even Costco runs are possible for the Spicy Curry’s powerful electric motor and the massive cargo-ready space on the bike’s sides and back. It can seat your younger kids, with low rails on the side, and features LED lights so you and your passengers stay safe. Of course, this is a bike that needs an electric boost unless you can push seriously massive watts, but thankfully, it comes with the Currie Centerdrive 500-watt motor that can make the bike go up to 28 miles per hour.
I have a pedelec and love it. I have three bikes, and I want to pedal, but when I have a meeting at night that is 7 miles away, take the e-bike. It is enough of a boost to keep me from wanting to take the car at the end of a long day. It’s fun. Also, the laws on e-bikes continue to change, but it looks like the pedelecs will be classified as bikes, whereas bikes with throttles or self-propelled speeds of more than 20 mph are starting to become classified as “motor” vehicles and requiring registration in some states.

Set the maximum speed limit of the throttle or pedal assist system. We can electronically lockout the speed to 20 mph to comply with states with Class 1 or Class 2 E-bike regulations. Just make this request in the notes section at checkout.
We believe that only our riders should control the power and speed of our Electric Bicycles, so all of our bikes are throttle controlled. We believe that controlling the speed and brakes on a bicycle are intuitively linked as an extension of the hand.
