As a rule the same performance benefit you can get from a transmission can be had by just using a bigger motor. The end result would weigh the same and give you about the same increase of power. BUT a bigger motor has fewer moving parts to brake and is simpler to install and maintain!
Colossus can run 20-30HP continuous with a good cooling system and their is signs showing it should take 50kw (67HP) for ~10 sec! Because of its efficiency maybe more but it will also depend on batteries and the voltage Splinter uses. Right now Splinter is running around 10hp or less. So once he ups the power he will have a fairly quick bike and hills should not be a problem!

And Dave who has some good deals on
STUFRC lipo and most other types of Lithium batteries you MUST know your individual cell voltages while charging and discharging.
Batteries of all kinds need respect they can burn your house down, so don't sleep with them under your bed or any other were you cant afford smoke or fire!
