George can have one- tho it will need a flywheel like a steam roller.
On the other hand i find turbo sessions really good, get a few training DVD's and or get a thumpin' music selection on yer ipod.
There are plenty of training routines availiable on the web- just mix it up a little.
You can get a great structured workout on a turbo- no stopping- no free wheeling- no junctions or traffic- plenty of sweat tho, get a fan.
