I got back into riding a bike a couple of years ago and bought a folding 20" e bike to carry in my campervan. But the bike proved to heavy to lift into the van. So I ended up using it locally. The bike was handy cos walking was painful due to a spinal issue. Anyway the bike kept me active till I started to have balance problems. Then I saw a guy riding a trike and it turned out he had cerebral palsy and he really liked been able to get out and about. So I ordered a e trike and love it. My wife who can't ride a bike had a go on it and loved it so now we have 2 trikes. I'm nearly 76 and wife a youngster at 72. We managed to get out in the local area till recently when both trikes developed clanking noises when turning. So now both trikes are back at the bike shop awaiting investigation and I'm not getting any exercise.
