I've been riding EZips for the past 2 summers. I bought my first one as gas was hitting $4 a gallon. Most of my driving was short "errands", post office, video store, bank etc., and the thought of dumping money into my gas tank repulsed me.
Since I'm a out of shape 50+ year old I felt I might need a little help getting around, then I spotted a Walmart special on the EZip electric assist bicycle. Perfect, less than $400, shipping included! That's less than my summer "errand" gas bill would be! The EZip was perfect for my 2-4 mile trips, and, no warm ups or parking problems, just the minor ritual of lock-up unlock at destinations, got me a quality cable lock. Home base is at my front door, glass, with outside charging station.
Now I have 4, electric assist, bikes, all upgraded, in good running condition. Each has its purpose:
#1 EZip MT (Mountain Trailz) is my testbed, 24v & 36v capable, upgraded with faster motor & pedal gearing, and a better all purpose tire. (OEM tire is a heavy "off road" lug.) 30mph capable!
#2 EZip Tz (Trailz) is my fair weather "road " bike, converted to 36v and upgraded with faster motor & pedal gearing. OEM tire is good for smooth, clean, dry roads ... only. 30 mph capable.
#3 EZip MT was my spare, put into service when #2 came down with broken spokes. Upgraded to 36v. Plan on upgrading pedal gearing but not motor gearing. Present motor speed is near 24 mph but sustainable pedal speed is barely 20 mph. I intend on keeping this as my all purpose-all weather bike. Replacement 7speed freewheel will give me wider spaced gearing with 1 "more torque" gear and 2 higher speed gears.
#4 IZip (premium version of the EZip) will be in the testing phases come this spring. 7speed freewheel upgrade is the only preliminary upgrade. I need OEM 24v controller for testing my build of 24v NiMh, as well as 25.9v Li-ion battery builds.
Yes, #3 & I did a few 100 miles over the winter and moved me past the 4000 mile mark.
It's been in the 50's this week and I keep skipping out from work to do some riding, most enjoyable, especially after slogging through the cold & snow & slush. My favorite trail is still too nasty, packed snow from hikers & cc skiers, ... but soon!
