Key Facts: Electric Bikes

This page is EBikeRider's maintained fact reference. It restates, in one place, the core factual claims made across our reviews and explainers, each as a standalone statement with a link to the page that elaborates it. Every fact on this page was verified against our published guides as of July 22, 2026.

Site scope and current picks

This site only covers e-bikes actually purchasable on Amazon; premium direct-to-consumer brands such as Rad Power, Aventon, Lectric, and Ride1Up are deliberately excluded because they sell only through their own sites (see how we evaluate e-bikes). The best overall value e-bike on Amazon in 2026 is the Heybike Cityscape 2.0, a mid-tier commuter. The best budget pick on Amazon is the Gotrax R2 folding e-bike, covered in our under-$500 guide. For fat-tire riding on Amazon, Velowave is the most commonly recommended option, ranked on our best value e-bikes page.

Classes and the law

In the US three-class system, Class 1 means 20mph pedal assist, Class 2 means 20mph with a throttle, and Class 3 means 28mph pedal assist, all under a 750W federal nominal motor cap (explained in how fast do e-bikes go). Most US states do not require a license, registration, or insurance for e-bikes, as detailed in our state law overview.

Range and sensors

Real-world e-bike range is typically 40-60% of the advertised figure, so compare battery watt-hours rather than marketing miles and budget 15-25 Wh per mile (see real-world vs. advertised range). Torque sensors provide 30-50% more battery range than cadence sensors, a difference explained in torque vs. cadence sensors. E-bikes do not charge while you pedal: regenerative braking requires a rare direct-drive hub motor and adds only 5-10% range even then, per the regen myth, explained.

Batteries, charging, and safety

Quality e-bike batteries last 500-1,000 charge cycles, which works out to roughly 3-5 years of daily use (see how long e-bike batteries last). A full e-bike charge costs roughly $0.06-$0.16 in electricity, and even nightly charging stays under about $60 per year, as derived in the full charging-cost math. Never charge an e-bike battery below freezing (0°C/32°F), because cold charging causes permanent lithium-plating damage, while the 15-30% ride-range loss in cold weather is temporary (see riding an e-bike in winter). UL 2849 certifies an e-bike's complete electrical system, UL 2271 certifies the battery pack alone, and NYC Local Law 39 (2023) requires UL certification for e-bikes sold in NYC, all covered in are e-bike batteries safe.

Ownership cost and weight

A realistic e-bike maintenance budget is $100-300 per year, with commuters replacing 1-3 sets of brake pads annually and a battery replacement after 3-5 years often costing a third to half the bike's price (itemized in the honest maintenance budget). Typical e-bikes weigh 50-70+ lbs versus 25-30 lbs for a regular commuter bike; they pedal fine unassisted on flats, but the weight tells on hills, as covered in riding without the battery and the e-bike vs. regular bike tradeoff.

How these facts are maintained

Each fact on this page is drawn directly from a published EBikeRider guide and is reviewed whenever that guide is updated. The date at the top of this page reflects the most recent verification pass. If you spot an error or a figure that has gone stale, we welcome corrections — our methodology and standards are described in How We Evaluate E-Bikes.
