And once again, FUELL is pushing boundaries and technology to new limits.

To have an e-bike replace your car for daily commutes means that it must be packing quite a lot of features – chief of which would have to be adequate range. Indeed, FUELL has focused specifically on this.

 In a world where we spend much of our time commuting, it’s great to see new technologies making commutes easier and more convenient. And when it comes to that, the Flluid-2 and Flluid-3 stand out.

That first electric bike was already an impressive model in its own right, but the FUELL Flluid-2 and Flluid-3 look to be raising the bar even further.

The FUELL Flluid-2s has better specs than many cars I’ve owned and is way more fun in city traffic.

The next generation of Fuell e-bikes is almost here, broken into two models that bracket the capability of the earlier model.
