Me thinks you may find the 'heavier bikes' are even heavier these days (the 2012-2015 model is
259kg), especially off road, over 60 in no time, with dodgy hips/knees and a recent arm break. Get a cheap 250 single traily you can tow or hitch bar mount to the 4x4 and then use it just for the real off road bits and to scoot around town with a simple milk crate cube on the back.
a/ You don't need to go fast offroad if exploring firetrails etc.
b/ They are cheap as chips to buy second hand, register and run.
c/They are truly light and capable off road at speeds up to 80kmh.
d/You have heaps of moola left over for other things, interests or a road bike if the urge strikes.
e/Over 60 in no time, with dodgy hips/knees and a recent arm break.
f/Big difference in riding on road and off road when over 50. What was rubber and bounced now shatters or swells up with any bump or fall like one of your pumpkins on steroids!
Now ignore me, buy it anyway and sell it on to me within a year!
