Hey Everyone,
Just after people's opinions on the motor for a commuter. The path is 14km each way (say 30km round trip) with *mostly* rolling hills/flat however there is 1 hill which is a steady incline for 1.5km. ( not sure on elevation, but its this stretch : https://www.google.com.au/maps/dir/-37.8673183,144.9865044/-37.854751,144.9821722/@-37.8598421,144.9896748,15z/data=!4m4!4m3!1m0!1m0!3e0 )
I've pretty much decided to purchase the whole kit from http://em3ev.com however there's so much talk here about durability/heat/chewing gears etc that I'm not sure who to believe. Some other threads suggest putting trans oil in a geared the hub to stop it chewing gears/ticking (I don't have the tools or skill for this).
I'll start with riding conditions... Melbourne has the most f*cked up weather patterns. During Summer we get heatwaves that last for 2 weeks where every day is over 40degC. During winter we sometimes get 2 day heat waves (35degC) between thunderstorms... Its generally good weather for the other 10 months of the year. Reading the other threads here says that I should 100% stick to DD motors to deal with those conditions as the heat would wear out a geared hub?
I was actually after a MAC 8T to run 50km/h @ 48v on a 29er/700c wheel. (Haven't decided on the frame). purely because its less visible and lighter than a DD hub.
shopping list for my original plan of a MAC 8T (paying extra for plug and play is alright)

UPGRADE EM3EV VERS. MAC , 500/1000W PICK'N'MIX KIT

Wheel : Rear
Wheel Type : 700C Alex DH19
Throttle : full twist
Battery : 50V 14S 14Ah samsung pack
http://em3ev.com/store/index.php?route=product/product&path=35&product_id=132
Can you tell me I'm heading in the right direction with the MAC 8T? Should I change to DD to deal with the weather conditions to cope with the few weeks in the year? or something like a 10T to climb the incline?
Thanks in advance.
