Hi there
We have bought a 2nd hand Nihola cargo trike (http://www.nihola.com/products/family.html) and I want to fit a mid drive kit to it. It will be my wife who uses it to pick up the kid from daycare, groceries etc. Daily it will run 12ish km with a 3% 1km hill. So she needs some help from the motor.
Seeing 250W is the only thing allowed on the roads here, I am looking at the Bafang BBS01 250W kit, but reading this guy's hands on installation of it on a Nihola: http://www.cairns-electric-bikes.com.au/bafang-250-watt-electric-bike-conversion-kit/ + the Bafang thread where some guy is giving warnings about any version that is not V1 or V4(?), I am not sure about it.
Our bike has a Sram 7S hub with freewheel, so with the larger chain ring in most kits we could probably balance it with a larger rear sprocket right? Most convertions I see, is on derailleur type bikes.
The Sunstar SO3+ is the "official" motor in the Nihola shop: http://www.sunstaribike.com/en/nihola-and-sunstar-the-ideal-combination/ but it is 2x as expensive as a Bafang kit...
Sunstar price for kit with 11AH rear battery in Copenhagen = 1180£ (most expensive, but close by if part of kit fails).
Sunstar price for same kit from http://www.electricbikesales.co.uk/ = 950£ (save 230£, but i'm guessing weeks for repair if something happens).
Bafang price with 13AH battery from http://eclipsebikes.com/ (saw someone mentioned them in a different thread) = 560£. This looks like a bargain, but battery must be mounted in cargo area + hassle with returns if needed.
Any advice?
