Interesting to hear everyone's experiences in this thread. I bought my Wisper last autumn and started commuting with it, then stopped for the winter (rural roads, 13 miles each way, unlit, wife not happy) but started again in the spring. The ride is hilly and roads are rough, and even with full assistance it's a decent workout, although it is getting easier. Since then, I have lost over 2 stone, got somewhat fitter, and rediscovered my love of cycling. I am now looking at the next stage - going back to unassisted biking. I can't decide between spending a bit of money on a mid-range road bike or hybrid, or spending a lot less on refurbing my old Raleigh Amazon MTB. No suspension (good), heavy steel frame, but bulletproof and with very wide gearing. I'm at a crossroads, and interested in anything people have to say on making the change to 'normal' cycling. If I get fit enough and go back to unassisted biking permanently, I will probably sell the Wisper, but I will always think of it as 'the bike that saved my life'. When I got it, I was 60, overweight and slowing down badly. Now I am 61, about half-way to my weight goal, and feel a lot healthier. Looking forward to the next few months, and maybe even riding through next winter, wife permitting. Keep the comments and stories coming!
