Interesting, www.olympiacicli.it have just released a potential game changer, a 900wh battery with a range of 290 kilometres and it weighs the same as a 625wh battery.
I'm seriously thinking of purchasing an e-MTB, I currently ride an Ibis Mojo HD4 which is fabulous, however, due to time constraints I sometimes need a quicker fix, I'm currently leaning towards the Norco Sight VLT1, available in March through Evans Cycles but I am open to suggestions.
Cheers
