Overview
A step-through commuter electric bike with a 1000W peak motor and a removable 48V 10.4Ah battery, built around a low step-over frame for easier mounting and a claimed 60 mile pedal-assist range.
More than one reviewer treats the stock mechanical disc brakes as a known weak point worth budgeting to upgrade, with one bike mechanic swapping in hydraulic brakes after a 200-yard stopping distance on the originals. That's a meaningful caveat on a bike marketed around safety and stopping power in its own listing copy.
- 1000W peak motor, 48V 10.4Ah removable battery
- Step-thru frame with adjustable stem
- 265 lb rider capacity plus 65 lb rack load
- Dual 160mm disc brakes
Who it's for
Commuters who want a step-through frame for easy mounting and don't mind doing some mechanical fine-tuning themselves, especially around the brakes. Less suited to buyers who want a bike that needs zero mechanical follow-up after assembly.
Pros and cons
- Step-through frame makes mounting and dismounting easier
- Digital display is easy to read and simple to operate
- Customer service replaced a defective headlight quickly
- Stock mechanical disc brakes underperformed for at least one reviewer
- Plastic-composite rims raise cold-weather durability concerns
- Tires described as narrow by one buyer
- At least one unit arrived with shipping damage
Performance notes
One reviewer clocked 23 mph in the third electric gear and called setup straightforward, while another, a bicycle mechanic by trade, found the stock mechanical disc brakes took roughly 200 yards to stop the bike until replaced with hydraulic ones. Customer service replaced a non-working headlight for one buyer without issue, and the step-through frame drew praise for making mounting easier.
