GIO bike controller
I recently purchased a GIO scooter, and as is a reoccuring theme on these forums -- I want to go up hills. I saw the instructions for the http://www.giobikes.com/Blogs/electric-scooters/E-Scooter-Controller-Directions/ "shunt mod" but honestly that just doesn't seem healthy for the batteries or the motor... and I suck at "man things" like soldering and such.
However, the article also mentioned just buying a replacement controller... that sounds like something up my limited skillset ally. However, I don't know what I should be looking for.
Also how bad is the shunt mod for your scooter? I mean if it doesn't make a marked reduction in life (vs getting a controller elsewhere) could I just take the instructions to my local computer shop or whatever, and say "here are the instructions, here is some cash, can you do this for me?" ?
Tl;dr what is the best method for a mechanically challenged guy to make his bike go up hills and get a little extra speed.
