Hi Allen Do you have the new 4A charger, if so Steve is bang on as usual! All the best David

Hi Allen Let's see if I can help? 1) Does the battery need the full 'conditioning' process, i.e. the 12-hour charge plus the 2 or 3 full discharges? (I've been emailing Wisper, but no reponse yet). I suppose my question is this: would Powabikes have done this process before delivering the...

Gee shucks! Thanks a million Larry, I can't start to explain what a massive boost a posting like this gives to us all here at Wisper. I have sent a copy of your review to the Wisper guys in China with a big letter of thanks! All the very best David :D

Hi Alastair! Welcome to the forum, it's a great place to keep in touch with customer's and sort out any problems they may be experiencing! All the best David

Hi Alex, I am sure there is as we use the light now on all our bikes. On the Bafang system used on the bikes you are questioning we don't use the light sensor but an on off switch on the handle bar controls. I would be happy to get a set sent over with the next container. All the best David

Hi Mike The light we use is different from in the ones in the manual as it works directly from the battery and has a sensor so the body looks like the basic as a switch has been made redundant.. I think that re-setting the LCD controls is simply turning the power off to the light and back...

Hi Mike, very good point re the Wisper Alpino lights, thanks, I will look into it and get back to you ASAP. All the best David

Thanks Andrew! All the best David

Hi Andy It would reduce the range by about 5%. But I think at your weight the longer range 14A controller would be perfect. Try both! Sorry the Alpino os only available in White. All the best David

No, not quite Bigbee, but good idea! We took a leaf out of 50 Cycles' book, I remember being massively impressed when I read that they had recovered a Kalkhoff from a thief who tried to order a new charger, they took the guys address and bike frame number. Realising the frame number...

Hi Andy Thanks for choosing a Wisper, I hope you have masses of fun and great service from the bike. Regarding your dilemma in choosing between the two bikes, as Eddie quite correctly says you should try both before you buy. There are several important differences between the 905se City...

Hi Bill You can take the rear wheel off the bike by disconnecting the motor by pulling the plug which can be found either in the controller box space (take off the half cone protector under the controller box) or on the rear frame near the back wheel, depending on the age of the bike. The...

Bike Radar See you at Brands Hatch Sue! All the best David

Boosts Hi Tex It boosts the max output about 15% and brings it to about 620W. All the best David

Kenda Electric bike tyres Hi The new tyres are starting to come through now, the beading are has been substantially toughened up and the rolling resistance is lower than on the old tyres. The new style tyres, protected by nylon and Kevlar are already on the 800 series bikes and to date and...

Thanks for the great report Mike! If the noise from the motor does not improve soon we will swap it out for you. Andrew, please let me know how the new controller affects the range. The 16.5a controller is available to anyone with the Alpino or XC tourer, just drop me a PM or an email...

Tiger Temple My Daughter was their last year, scary! All the best David

Well done Andrew and I had a very productive meeting in London earlier this week when he showed me his new frame design and new colours which will apply to all future Oxygen bikes. Based on this we have both buried the hatchet and we at Wisper wish Andrew and Oxygen all the very best in the...

Hi Bill I am checking out Support@wisperbikes.com now as it is not one I use. If there is a delay try the one for Norman at the bottom of this reply. All the best David

I love the lime lite and of course "I'm smarter than your average Bear" Now where are those Pickernick baskets Booboo. :D Best regards David
