No noise means no annoyed neighbours and every chance you will be riding longer than a petrol bike because no one will chase you away for annoyiong them. Typical ride time about an hour. Typical recharge time about 2 hrs.
No spark plug, no clutch plates, no oil changes, no air filters means you will be fixing less and riding longer and it will be cheaper to maintain (no spending on the latest exhaust pipe or piston kit or race fuel)
No HT lead or air intake means shallow streams can be ridden without the fear of hydraulicing your bike or drowning out (no you won’t get electrocuted!)
Light weight means less fatigue and more flickability when the going gets tight
High power full torque right from zero rpm means no bogging out of turns
No kick start means you can just get straight back on after you have come off without trying to kickstart a bike with a flooded carburettor
No hot exhaust means no danger of burnt legs or feet
Swappable battery pack means you can be quickly back riding if the battery runs flat ( £850 extra charge )
