Overview
Qlaway sells the BK20 as a two-seat capable fat tire electric dirt bike, available in 500W and 750W versions with a 48V removable battery rated for 40 to 70 miles depending on capacity. It's built for riders who want one machine for paved commutes and light off-road trails, including carrying a passenger.
Off-road capability came up unprompted in multiple reviews, with buyers surprised at how well the fat tires handled sand, dirt, and grass. Complaints were lighter here than for some comparable e-bikes, mostly limited to a poorly designed phone mount.
- 750W motor (1500W peak) with 30-degree climbing capability
- 48V 18AH removable battery for up to 40 miles per charge
- Full suspension with four shock absorbers front and rear
- Cruise control, LED headlights, and turn signals
Who it's for
Fits riders who want an e-bike capable of both road commuting and light trail or beach riding, including those planning to carry a passenger on the rear seat. Less suited to buyers who need the absolute lightest folding bike, since full-suspension bikes in this class tend to be heavier.
What buyers say
From Amazon customer reviews.
Reviewers consistently praised how easily the bike assembled, its stability on sand, dirt, and grass thanks to the fat tires, and a comfortable seat suited to carrying a second rider. Seller communication and shipping speed also drew praise. The one design complaint raised was a poorly designed phone holder.
Strengths and trade-offs
Drawn from this product's published specifications.
- Handles sand, dirt, and grass beyond expectations, per reviewers
- Full suspension with four shock absorbers for mixed terrain
- Extended rear seat and cargo capacity for a second rider or gear
- Assembles in under an hour for most reviewers
- Phone holder mount was called out as poorly designed
- Heavier build typical of full-suspension fat-tire e-bikes
Performance notes
The 750W motor (1500W peak) and 80 Nm of torque are rated for climbing grades up to 30 degrees, with the 48V 18Ah pack sized for the model's higher advertised range. Four shock absorbers front and rear are meant to filter vibration across mixed terrain, and cruise control engages automatically after 8 seconds of steady speed, disengaging on any acceleration or braking input.
