    Futureproofing Batteries

    Hi Wonderpup, Good question! The simple answer is that we will be keeping the same connection system on all our bike with batteries mounted behind the down tube. As long as we keep to 36V any new battery will run as well through the system as the one you have at the moment. As far as...

    Which bike for off-road?

    Bling? No sir it's not sir! Currently our warranty does not discriminate, however if the bike had been involved in a crash we would have to take a view. The 906xc bike is not simply bling it really is very tough and has superb equipment. The Vogue magnesium air shocks can be pumped...

    Fastest climber?

I find it amazing that although these people insist they are not copying our bike, the...

    Fastest climber?

    Exactly that Tim, you set the bike to say 100/120 beats per minute and the assist will not kick in until it reaches 120 and stays with you until your heart drops below 100. It also tells you how many calories you have burned on a training session or gentle cycle ride. All the best David
