I folded the 20 INCH ELECTRIC FOLDING BIKE BTWIN 500E – GREY BLACK and put it in my car trunk for a short getaway. It served as my commuting tool when I arrived at the IHG hotel I had booked. The roads on this trip were mostly flat, with some short uphill and downhill segments.
When I rode this electric bike, the overall riding position was very comfortable. The geometry is just right, and the soft saddle perfectly conforms to my body, providing ample support and reducing pressure. The ergonomic handlebars felt comfortable to grip, providing a secure hold.
The excellent motor provided a continuous power output, making each pedal stroke feel effortless. The Shimano transmission components offered smooth shifting and reliable quality, making them dependable components.
The aluminum V-brake calipers provided strong, progressive braking, allowing me to easily slow down and come to a stop. However, this type of braking may not match the performance of hydraulic disc brakes. Nevertheless, the braking capability is sufficient for this electric bike designed for commuting and leisure rides.
Finally, I maneuvered through the city streets with this bike. The smaller wheel size and compact frame offered a nimble riding experience, allowing me to easily navigate the streets.
