wow a slew! this proves we were getting reamed pretty good at the onslaught,a good bike mechanic can overcome some of the drawbacks,before when the price was starting to drop I bought a rear suspension( cant remember the brand around $1k) it was dang good wish I would have kept it,if you helped it,it would help you,the rear shock actually functioned the 500 watt motor would peak at 625,14.5 battery it was actually a good deal-even though I bought it by mistake,if you were willing to help it would it would drag me up driveways that were hard to walk up.
