Confidence: limited - limited rating history.Last refreshed Jun 21, 2026. Data-computed, not a hands-on test. Compiled by the ProductDome Research Team.
Overview
A dual-spec electric dirt bike sold as the A20 (2000W peak, 30mph, 48V 18.2Ah) or A20 Pro (3000W peak, 33mph, 52V 22.5Ah), with 17 inch fat tires and full suspension. Built for adults and teens wanting an off-road styled ebike.
- 2000W/3000W peak motor options, 30/33mph top speed
- 48V 18.2Ah or 52V 22.5Ah battery
- Up to 100 or 120 mile PAS range
- 17x4.0 fat tires, dual hydraulic suspension
Who it's for
Suits riders between about 5.4 and 6.6 feet tall who want a choice of two power tiers on an off-road styled ebike and are comfortable checking for shipping damage on arrival. Shorter riders may want to check seat height first, since one 5-foot-5 reviewer found their feet did not fully reach the ground.
What buyers say
From Amazon customer reviews.
Positive reviews praised fast delivery, strong welds, powerful battery and the 17 inch dirt-bike style tires and rims, with one reviewer specifically recommending the Pro version. Complaints included a cracked reflector on arrival, unhelpful printed instructions requiring a YouTube video, a seat too tall for a 5-foot-5 rider, missing turn signals on one unit, and a battery that did not reach its claimed 35 mile range.
Strengths and trade-offs
Drawn from this product's published specifications.
- Choice of 2000W or 3000W power tier
- Dual hydraulic disc brakes with fast response
- Full suspension for off-road use
- One buyer's unit arrived without turn signals
- Reflectors reported cracked or loose on delivery
- Seat height too tall for a shorter 5-foot-5 rider
Performance notes
The A20's 2000W peak motor delivers 110Nm of torque and Aonpo states it climbs 30 degree hills, with the Pro's 3000W setup adding to both torque and top speed. Dual hydraulic disc brakes are rated for a 30 percent stopping-power increase over standard brakes with a 2-second response, useful given the bike's higher speed ceiling. A reviewer's range claim did not match expectations in one case, and another reported missing turn signals, so verifying full functionality against the listing on arrival is worthwhile.
