That moment when another cyclist rides by going uphill without seeming to break a sweat may be your first encounter with an electric bicycle. The dead giveaway is the lithium-ion battery mounted above the rear tire or under the seat. More fully integrated from a design standpoint are batteries attached to the down tube under the handlebars. E-bikes have become more popular as a safe, socially distanced alternative transportation option that’s also environmentally friendly. Be advised: prices vary widely, ranging from Rad Power Bikes’ Metro bike model (radpowerbikes.com), which goes for $1,100, up to $10,700 for one made by sports car maker Porsche (shop.porsche.com). Here are three things to consider before buying.
1. Type
E-bikes come in two flavors. One is the pedal-assist variety, handy for uphill climbs, but using pedal assist on straightaways actually amplifies the power and efficiency of normal riding. The level of pedal assistance is selectable. The other option is a full-throttle assist on the handlebar, which is a close second cousin to a motorcycle in that the outer range of speed is as high as 28 mph. Some e-bikes are performance-oriented with the ability to shift gears, while others are single-speed only.
2. Weight
At around 45 pounds, e-bikes weigh significantly more than standard bicycles, thanks in large part to the battery and motor—something to consider if your commute includes a flight of stairs. Keep in mind that the greater weight and speed means you’ll want to check the brake pads more often. Weight also matters for specialty models. Rad, for example, makes a 77-pound cargo RadWagon ($1,700) with a 350-pound capacity that can be used to haul everything from kids to groceries.
3. Battery Life
Battery recharging generally takes between two and three hours. Battery capacity is measured in amp hours (ah), with a typical range of between 10 ah and 21 ah. The higher rating translates into greater distance under power, and about 45 miles per charge as an average. Batteries are removeable so you can charge them at your destination, for example, before the ride home. —Frank Vizard
