Electric BMX Bike

BMX stands for bicycle motocross, a name that traces back to the sport’s roots in imitating motocross racing on pedal bikes. A BMX bike has a compact frame, smaller wheels, and a single-speed setup, which together make it quick to handle and easy to move around. You’ll find them on dirt tracks, at skateparks, and around town. retrospec builds its electric BMX bikes on that same platform.

An electric BMX bike pairs a classic BMX frame with a motor and battery, so you keep the BMX handling while gaining power for hills and longer rides. Both retrospec models use a 750W planetary geared rear hub motor and a 48V/500Wh LG 21700 battery, with five levels of pedal assist, a thumb throttle, and a walk mode. Top assisted speed is 20 mph.

Frame geometry remains similar, but an electric BMX bike adds a motor, a battery, and the weight they bring. A standard BMX bike is light and entirely rider-powered. The Joe Rev 2 BMX Electric Bike gives you assistance up to 20 mph across five levels, plus 180mm disc brakes sized for the extra speed and mass. Charging and range become part of ownership.

Usually, yes. Motorized BMX bike is older terminology that most riders now use to mean an electric BMX bike, though it sometimes refers to a gas conversion instead. Everything in the retrospec electric BMX bike collection is battery-powered and built as a complete bike, not a conversion kit, and both models are certified to UL 2849 and UL 2271.

You get BMX handling with motor assistance. The compact frame and wide 27.5 by 3 inch tires give you agility and a large contact patch for stable braking, while the 750W motor takes care of hills and distance that would otherwise wear you down. Next to an electric commuter bike, the ride feels more playful while still covering real ground.

Long-distance comfort is the trade-off. These are minimal, single-speed bikes with a rigid steel fork and no suspension, so they ask more of you over a long ride than an electric city bike would. They also lack rack-and-fender mounts, making cargo carrying harder. Both retrospec models are rated best for pavement rather than rough terrain.

Yes. Both retrospec electric BMX bikes are built for adult riders, with a 350 lb recommended weight limit, a 31 inch standover height, and 27.5 by 3 inch wheels rather than the 20 inch wheels common on youth BMX bikes. To check your fit, measure your inseam and compare it to that 31 inch standover, aiming for roughly an inch of clearance over the top tube.

Wheel sizes across the category run from 20 inch up to 27.5 inch. Both retrospec models use 27.5 by 3 inch cruiser tires, noticeably larger than a traditional 20 inch BMX wheel. The extra volume smooths out rough pavement, improves traction, and widens the contact patch for better braking. Both come in a single frame size with a 31 inch standover height.

The Joe Rev 2 BMX Electric Bike and the Joe Rev BMX Electric Bike both carry a recommended weight limit of 350 lbs, covering you plus anything you’re carrying. Limits vary by manufacturer, so check the specifications tab on anything you’re comparing. Staying inside it protects the frame, wheels, and brakes over time.

Across the category, expect prices of roughly $500 to $3,000, driven primarily by motor size, battery capacity, and frame material. retrospec electric BMX bikes sit in the middle of that range, and both include free shipping along with UL 2849 and UL 2271 certification. Current pricing for the electric BMX bike collection is listed on each product page.

You can spread the cost over time. retrospec offers monthly payments through Affirm at checkout with 3, 6, or 12 month terms, plus the option to split your order into four interest-free payments. Your monthly figure depends on the bike, the term, and approval, so use the amount shown on the product page you’re buying. Full details are on the financing page.

Joe Rev 2 is the current generation. Both share a 750W rear hub motor, a 48V/500Wh LG 21700 battery, five pedal-assist levels, a throttle, 27.5 by 3 inch tires, and a 350 lb weight limit. Joe Rev 2 adds a longer rated range, an LCD display in place of the LED unit, anti-vibration front rotors with an integrated bell on the lever, and three colorways instead of one.

Both retrospec electric BMX bikes reach a top assisted speed of 20 mph, whether you’re on the throttle or using pedal assist. Past that point, the motor stops adding power. Federal guidelines cap assisted speeds at 28 mph, and rules vary by state, county, and city, so it’s worth checking what applies where you ride before you head out.

Range depends on terrain, rider weight, and how much pedal assist you lean on. The Joe Rev BMX Electric Bike is rated up to 48 miles on a full charge, and the Joe Rev 2 BMX Electric Bike up to 60 miles in its specifications. Both run a 48V/500Wh LG 21700 battery that charges on or off the bike.

Both retrospec electric BMX bikes use a 750W planetary-geared rear hub motor running at 48V, paired with a 500Wh LG 21700 lithium-ion battery and a cadence sensor. That setup offers five pedal-assist levels, a walk mode, a thumb throttle, and a 20 mph top assisted speed. Across the wider category, motors typically range from about 250W to 750W.

Most electric bike batteries retain useful capacity for several years of regular riding before the range noticeably drops, and how you treat yours matters more than the calendar. Keep it away from extreme heat and cold, avoid running it fully empty, and store it partially charged. If you ever need one, a replacement Joe Rev battery is available.

Plan on a few hours from empty using the charger that ships with the bike, which is a 48V/2A unit on Joe Rev 2. The integrated battery on both retrospec electric BMX bikes charges on or off the frame, so you can bring it indoors if the bike lives in a garage or shed. Charge somewhere cool and dry, out of direct sun.

No, and that’s by design. BMX frames stay rigid, electric ones included, and both retrospec models pair a 6061 aluminum frame with a rigid steel fork. Suspension adds weight and complexity that work against a BMX bike's direct, responsive feel. The wide 27.5 by 3 inch tires absorb much of the road instead. For a softer ride, look at electric fat tire bikes.

Pavement is where both retrospec electric BMX bikes work best, and each product page rates them for pavement ahead of gravel and all-terrain. The wide tires, Tektro mechanical disc brakes, and rigid steel fork handle streets, bike paths, and packed surfaces comfortably. Where you’re legally allowed to ride varies by state and sometimes by city, so check local rules first.

In most places, yes, though it depends on where you live. Some states treat electric bikes exactly like regular bicycles, while others limit them on sidewalks or shared paths. Both retrospec electric BMX bikes top out at 20 mph assisted, which sits inside common state limits. Check the People for Bikes state law guide and confirm your city’s rules before your first ride.
