EZip - IZip Trailz! The EZip is a great deal. Let me expound on its capabilities, potentials and limitations.
First, I would like to assign definitions.
Ebike - Electric Bike - A bicycle style vehicle, designed to be powered by an electric motor.
EAbike - Electric Assist Bike - A bicycle, modified by adding an electric motor, to assist the pedal power of the rider.
Hybrid - Bicycle, designed to be powered by pedal or motor or both.
I have put almost 4000 miles on my various EZips, trying many different modifications and enhancements.
In its oem form, I would rate them as:
"poor" Ebike - "fair" acceleration, 7 mile range
"good" EAbike - "very good" acceleration, 15 mile range; dependent on "assist"
"good" hybrid - great, for the price, loses points due to excessive weight as "bike"
Great deal, as any of the above, based solely on price.
Getting Started!
E-Zip Mountain Trailz 1 year 1600 miles - report. EZIP - www.EcoForumZ.com
E-Zip "Trailz" VS "Mountain Trailz" EZIP - www.EcoForumZ.com
Basic performance tips:
1. Inflate tire to maximum recommended inflation pressure.
2. Pedal assist getting up to speed, and on hills.
3. Begin coasting well before you have to stop, Stop signs etc.
OEM battery Tips:
1. Do not deeply discharge battery.
2. Recharge battery immediately after use.
Sealed Lead Acid (SLA) battery care - www.EcoForumZ.com
Upgrades:
Re-gearing for higher speed.
Replaced the 20T motor side freewheel with a 16T. This mod increased speed from 16mph to 20 mph. Cost of parts $20.
20mph+ from EZIP 24 volt OEM pack! - www.EcoForumZ.com
Battery upgrade 36v:
Upgraded to 36v. Speed increases almost 50%, from 16mph to, nearly, 24mph. I have run 2 different bikes with no motor modifications, for 1000 miles each, with no problems! Probably due to these factors:
1. I always pedal assist getting "up to speed".
2. I tend to cruise at the "legal" 20mph, rather than "full throttle" 24mph.
3. Always pedal assist on hills, and resist full throttle.
Unfortunately, presently available bikes require replacement of the 24v controller, also. I recommend replacing the throttle with one that matches the new 36v controller.

25.9v Lithium-Ion battery:
2 great advantages are small size-weight and great capacity - range!
Uses OEM 24v controller, as tested on 2 bikes.
Drawback is price, unless you "scavenge" your cells.
Also, seems adversely affected by cold, restricted discharge rate.
36-37v & 25.9v reports are documented here:
