Here's my view/stance on this. Tyke, Banner or Red & Green.
Local, to me, mobility experts were seen with regards electrifying a recumbent trike & possible benefits for the wallet. These same experts have various companies/councils recomending them. Plenty of others about, it's just word seems to have got out about them.
I found myself being steered in the direction of one company already mentioned on here. Not exactly local, but better placed, in their opinion, despite them doing some electric assist trikes, to give a more complete solution to what I was after.
They could quite easily have said "this'll do the trick", and kept any sale in house. Instead they kept their reputation, directing me towards a person who posts on here. They didn't know that part.
