Although with a bit few improvements from the original Mantra, the Mantra V2 has a much better experience, especially for novice riders.

Handlebar Brakes

The one feature that stands out in the Mantra Fixie is the handlebar brakes. This feature was added specifically to enhance safety for newbies when slowing down. With the Mantra V2, there are some improvements to the braking system compared to the original Mantra.

While reverse cycling can slow it down, this bike comes with front and rear Promax brakes. These are high precision brakes that can be controlled over the handles. However, backpedaling is just as effective if you get used to the fixed-gear bicycle.

Coasting on a Fixed Gear

Another important feature of the Mantra V2 is its flip-flop hub. Although it is expected that a fixed-gear bicycle moves forward with every pedal, the Mantra V2, just like the original Mantra, still caters to single-speed riders. With two cogs on the rear wheel, you can easily shift between the single speed and the fixed-gear riding.

To shift between the two, all you have to do is remove the back wheel, flip, and you are set to coast. This is a key feature of the crossover since it takes time for most novice riders to get used to the fixed-gear cycling energy needs.
