My intro to ebike was a secondhand powatrike which pulled a dog trailer and coped with shopping trips etc until i pretty much wore it out. Then my dad installed a kit from bob's bikes onto a normal trike and it's been a nightmare. Problems with wiring, fuses, ignition and a lot of unidentified nervous breakdown s. My brother just went to rescue it after it cut out this morning, on the way back from a short trip to a computer repairer. I said I was going to cut my losses and get another kit installed and he said that would be pointless because no motor would cope with the demands I put on it. I can't drive for health reasons and the bike is my only hope for any sort of independence. It's used daily for a round trip of about 4 miles round trip pulling a trailer with about 30 kg of dogs in, a bit further twice a week when I take one dog to agility - but its a totally flat trip, and some shopping trips, which can be heavy to carry back. It's a throttle type kit but I always pedal too. So if I opt for a new kit are there some which would be more likely to cope better? I'm grateful for my free bus pass but it's pretty much useless unless I want to go into the city between 10 and 3
