Got this baby specifically for Geocaching where locked gates etc impede access and to save walking of course....it's a Lancaster Electric motor driven 200w with 36v battery of pedal assisted rear hub driven power. Have a Garmin GPS60CSX which mounts on the handle bar with a garmin mount...works a treat. Have only tested it on one trig cache.....but performed really awesome.
This bike is pretty weedy in comparison to those listed...but hey...it does have the advantage of being able to go into reserves, bike tracks etc that it's petrol driven cousins can not....and is also a 21 speed MTB.

Rated: for Overall Experience.
