Incredible piece of kit

The storm is one of the most refined bikes out there and I never truely understood how sensational this bike was until I jumped on one. The performance, tech and build quality in this machine is second to none and unrivalled, you can really see some serious years of development has gone into this one. The removable battery, reverse and slip reduction are all well thought out little features that make this bike more functional in scenarios you never thought were needed. With the fast charger I’ve been able to achieve a full days riding with a top up charge over lunch no worries. If your looking at one of these you will not be disappointed.
