Problems with Traditional Non-Folding Bicycles

Riding the Vektron S10 is very easy and intuitive. It handles relatively well and responds snappily to your adjustments and steering directions. In terms of comfort, the Vektron S10 allows you plenty of space to sit and you can adjust the height of the bars a fair distance, so finding your optimal position should only take a few minutes.

Kids and adults can find comfortable ranges with little difficulty.

Controlling the bike is easily since all of them are situated with one hand, letting you balance or carry something with the other. The brakes respond quickly and easily with a finger’s worth of pressure; no need to squeeze tightly to get the bike to stop on a dime.

While the battery isn’t designed for long-range hauls, during the ride the motor feels smooth and faultless. The actual ride itself feels casual and easygoing.

We also really liked the bright lights on the front and back, and both sets are integrated. Nighttime visibility isn’t an issue with the e-bike.

Benefits of Folding e-Bicycles

The Mid-Drive motor for the Vektron has a number of great design advantages. For one, its position allows for easy folding and carrying. Plenty of e-bikes have motors that are too heavy or unbalanced, which make carrying the bikes difficult. Not so with the S10 mid-drive motor. The well-balanced weight and positioning keep your riding smooth and flat too.

Learning how this e-bike feels in terms of heft and weight is easy when the motor is so well-integrated into the rest of the frame.

In addition to this benefit, it’s powerful and even, delivering reliable power to the electric bike throughout its battery’s lifespan. Even when it starts to reach the bottom of its power levels, it’ll maintain good speed and help you get where you need to be.
