Crew Dart20
The Crew Dart V3 20" brings all the upgrades of the 24" model into a tighter, more compact build. Same bike life energy. Just built for riders who want more control without giving up performance. Class 2 compliant for a safe and legal ride. With a top speed of 20mph and a range up to 20 miles using throttle, and 25–35 miles with pedal assist, the Dart 20 delivers the power and versatility you need to ride farther, cruise longer, and stay in control.
The compact 20" setup offers a lower standover and a more agile, easy-to-handle feel, making it perfect for tighter spots and technical riding. An upgraded chromoly steel frame with refined geometry delivers a stable, responsive ride, while the new bench-style saddle improves comfort and balance with a clean, locked-in feel for longer sessions.
A 750w rear hub motor paired with a 48v / 10Ah battery delivers smooth, punchy power, backed by hydraulic disc brakes for confident stopping control. Fat 20" x 4.0" Crew Takeover Tires add grip, shock absorption, and street-ready style—making the Dart V3 20" a powerful, approachable choice for everyday rides and full ride-outs. Recommended for riders 4'10"-5'10".

Write a ReviewNew e-bike Dart20
My son loved his Dart20. He's 11 and it fits him really well. The bike is faster than I thought but I think you can throttle down the speed on an app. My oldest son is looking forward to the latest Dart release. He's excited about the suspension.
Crew Bike serves the commuter purpose
Sound bike that gets my son around the neighborhood to practices and school
Good bike
My son loves it
Great bike tons of speed
Bike is pretty awesome. We use it as a pit bike at the motocross tracks. Eco has enough power to move the bike with ease which definitely helps it last a full charge for the whole day with enough left for the kids to have fun also. My kids rode it on race mode for 3 hours before using up the battery. I'm tall so I should have gone with the 24" model but this one works great. I'm in no way disappointed.
Great bike!
Got this for my son for junior high graduation. He is on the shorter side 5’2” so the size was perfect. He loves the bike. Well built and looks great. Looks better than all the macfox’s we see around. Only downsides 1. No key to start the bike. 2. There is a bit of lag from hitting the throttle to when the bike accelerates. Definitely not deal breakers.
