Fiido D4S Description

If you're looking for a lightweight (41 lbs), compact, and affordable folding electric bike, you have to check out the D4S from Fiido. The D4S is a great bike for people with limited space, like RV campers, and others who like the convenience of not having to carry their bike on a rack. The D4S folds at the center of the bike and at the base of the tiller, letting you store it in a car trunk or back seat.

The Fiido D4S can be ridden like a conventional bicycle, using the 6-speed Shimano derailleur to shift gears as you ride. But when you need a boost of power from the 250W rear hub motor, the D4S will not disappoint. It features both a 3-level pedal assist system (to help you while pedaling), and a right-side twist throttle which allows for riding with no need for pedaling.

As always, we recommend checking out independent ebike reviews before making an important buying decision (especially when shopping for a budget electric bike, where corners are often cut). Here we have Chris from the TechTablets YouTube channel, giving a detailed and honest review of the Fiido DS4.
