Deep cell battery added- had 3 (36V, now has 4 *48V) Yellow 1 person convertible, opens like a "clam shell". Belt drive with higher gearing than stock. Has dyeing DieHards now.
Current Mods:
Hard to improve! Moved all four onboard chargers and have a much larger external booster; just in case! Rapid charge.
Planned Mods:
I wish it was a bit easier to open; very heavy and solid. No other plans. Hard to get tires for it in this country, but got American equivalent Pirelli tires in Ohio. Will need batteries eventually. Exceeds speed and weight limits a stock City-EL is built for.
