Further Details & Reviews

Uphill Racer!

I’ve only had my Wisper E-bike a few days, but so far, so good! It’s enormous fun, and I find that - at the age of 72 - I can whizz up some of the steeper hills in Cardiff quite effortlessly. On a more serious note, I wasn’t using my old, non- electric bike much at all, but my new Wisper had made me want to get out and ride, and I suspect it will provide opportunities for using the car a bit less.
Build quality appears excellent, and my Wisper had already prompted many admiring glances. I’d recommend Wisper to anyone looking to buy an e-bike.

Just a fantastic bike (Tailwind)

Right, lets deal with the one negative first. I initially had problems with the battery switching off when still showing half full, hence the four stars, have to be honest about these things. The battery was replaced and a new one delivered, all at no charge and that's sorted that.

This bike is a joy to ride. Comfortable, gearing exactly right for combining with the pedal assist power, nice fat (hard to puncture) tyres that can deal with any surface. I'm commuting the 20 mile round trip to work on a combination of road/badly maintained road/cycle path/ trail with quite a few hills and it eats it up (with only one short section where I need to use the highest assist setting) - and I'm a 57 year old who weighs getting on towards 14 stone, so the fact I'm getting 50 miles out of one charge (on this new battery) is impressive

I'm doing this three days per week and I've stuck 560 miles on it in the last 12 weeks with a grin on my face the whole time. (The only reason I haven't done more miles than that is the battery issue at the start, being away for a bunch of weekends and on holiday for two weeks).

Bloody brilliant.
