9 reasons not to buy

Testers fail to reach the claimed 20mph, topping out between 15 and 18mph.
Viribus advertises a 400lb payload, but the owner's manual lists 330lb.
The motor takes three to four seconds to re-engage after braking.
Testers experience ghost pedaling from PAS level 3.
One reviewer says the trike starts to tip when turning at just 6mph.
The battery mounts wobble on two test bikes.
A 200lb rider bottoms out the suspension seatpost, even at its stiffest setting.
The FC1 trike lacks a reverse mode.
Assembly is more difficult and time-consuming than advertised, and includes fitting the front brake caliper.

Bottom line

The Viribus FC1 is a folding electric tricycle with a 750W motor and a 706Wh battery. Testers praise the comfortable saddle, strong hill climbing, and excellent accessory package. However, ghost pedaling is an issue, and quality control issues appear across units. The weight makes folding difficult, and the folded trike is bulky. Opinions are split on the Viribus FC1: two reviewers rate it highly, but others are disappointed by its shortcomings. That said, all competitors at this price point have their own set of issues.
