im disabled i ride a recumbent trike and pull a trailer, i run down the roads picking up aluminum and whatever i find that can be sold, i know if i can increase my range i can increase my paydays, i would like to motorize my trailer, i had thought i could just use a electric hub on my bob trailer but i dont want all that stuff on my trike, i'd like something that is just a push button, if i need a little push just hit a button and let off when im over the hump, doesnt have to be a hub motor either, any ideas? thanks
