Re: How can I improve this?
you would be better off just replacing it ..
Its a bike resembling a full suspension mountain Bike.. but Aka, a Bike Shaped Object..
a proper FS MTB is in the $2K+ range.
Better will be a Hybrid.. Narrower, easier rolling wheels ... without being overly thin.
and a reasonably comfortable handlebar that many are satisfied with ...
Visit a proper Bike Shop and take some test rides. the quality of bikes in those shops
is better than those coming out of mass merchandisers .
And they, the shop staff, are there for service after the sale ..
