This is a summary of a 3 ½ year field-test of an NCR lithium-ion battery. For discussion of our batteries in general refer to discussion 4, “Battery technology”. For 2022 we upgraded from NCR to INR chemistry (greater range) and are in the process of repeating this endurance field-test for these batteries (so the actual […]

Our bikes are all motor assisted at the front wheel, as opposed to the rear wheel or at the crank. A front wheel motor (1) facilitates even weight distribution and (2) allows us to use internally geared hubs (low maintenance and ease of use) in place of derailleur gearing at the rear. For good weight […]

E-bikes are one of the best energy choices available for alternative urban transport…so much so that e-bikes vie for low-energy supremacy over conventional pedal-only bikes. Lower than unaided walking as well! “The energy cost of electric and human powered bicycles” (UBC Applied Science 262, April 2004 paper by Justin Lemire-Elmore), concluded that conventional “pedal-only” bikes, […]

Like most e-bikes on the market, ours use lithium-ion batteries. There are, however, many types of lithium-ion battery, and improvements in their chemistry are made every few years. Our ongoing battery test program keeps us at the state-of-the-art. Over the last decade we have upgraded our battery chemistry 4 times to ensure we are using […]

No, too many drawbacks. Regeneration (recharging from pedaling or when going downhill) is not of much benefit to e-bikes, as it is with, say, hybrid cars. With our e-bikes you draw a net amount of energy from the battery pack to assist you riding. You then replenish this energy from household power, rather than by […]

A half-grip twist throttle on the left side of the handlebar controls power to the motor. Like on a motorcycle, twisting the throttle provides fine control proportional to the amount of power assist. For safety, the throttle spring returns to zero assist (no power) when released. The half-grip allows the rider to comfortably maintain throttle […]

Range – without pedaling 30 km; with pedaling 50 to 100 km. The standard Pedal Easy battery has a nominal energy capacity of 320 Watt-hours (at 300W discharge rate). For the average-weight rider, when battery power is used only to supplement pedaling and help on steep up hills, this translates to about 50 km of cycling […]
