DYU D3F 14 Inch Mini Folding Electric Bike

The DYU D3F 14 Inch Mini Folding Electric Bike is a compact and affordable electric bike designed for short commutes, everyday journeys and riders who want an e-bike that's easy to store and transport.

Powered by a 250W motor and a 36V 10Ah lithium-ion battery, the DYU D3F provides smooth electric assistance up to 25km/h (15.5mph), with a claimed assisted range of up to 50km (31 miles) per charge. Its combination of compact dimensions and electric assistance makes it particularly well suited to urban journeys, commuting and leisure riding.

The D3F's 14-inch compact design makes it easy to store where space is limited, while the folding handlebar reduces its overall size for transporting in a car or storing at home. At 19kg, it's considerably smaller and more manageable than many full-size electric bikes.

For confident everyday riding, the DYU D3F features front and rear disc brakes, durable 14-inch tyres and an integrated front headlight for improved visibility. An LCD display provides a clear indication of the remaining battery level, while the adjustable saddle allows the riding position to be adapted for different rider heights.

Despite its small size, the D3F has a maximum load capacity of 120kg, making this compact electric bike a practical option for a wide range of riders.

A range of optional accessories is also available for the DYU D3F, including front and rear baskets, a child seat, helmet and bike lock, all sold separately.

Compact, practical and excellent value, the DYU D3F folding electric bike is a great choice for anyone looking for an affordable mini electric bike for commuting, leisure trips or everyday local journeys.

DYU manufacturer warranty

My first Ebike

No problems with my bike I’ve ridden over 600miles all good. Love it

Great E Bike for the price you pay for, Guaranteed.

D3F is really worth buying for the price that it is. If your looking for something exciting , small, comfortable, powerful motor, fast , and is easy to assemble in under 5mins. I say it can go about 20 - 25 mph. I weight about 165 and it’s no problem. I still feel the fast speed it puts out like 20 plus mph like nothing. I even hike my 4 yr old son who bout 45-50 lbs , and still goes fast. Very good motor. I use it for just cruising around my neighborhood everyday just to enjoy the outside . I really recommend this bike if you love speed and power . You’ll be Satisfied for what you’ve paid for .

Excellent minibike!

The bicycle works very well, it is very practical, I am very satisfied with the purchase made.
But I didn't receive the basket that was included when I bought it.
How long should I wait for it to be sent to me?
