2. Caught a 2nd on sale a couple months later. - <$300 delivered
3. About Christmas time there was an absolute bargain on a 2008 eZip Trailz. - about $125 after I sold the battery & charger
4. Couple years later there was a "new, minus battery", 2009 eZip Trailz LS. Too cheap to pass up! - ~$225 delivered

6. 2013 Trailz LS got listed (accidentally?) at $308 ... so had to get one.

Rundown
#1. 2008 eZip Mountain Trailz - 3500 miles
Replaced batteries in pack once. Then tried 20s1p D cell 6Ah NiCd, then 20s2p, then swapped to 36V SLA.
Suffered broken spokes and received a warranty replacement wheel, never used on that bike, kept replacing spokes till got bored so, when controller died I switched to 2nd 2008 Mountain Trailz.
Needs:
Rear wheel-motor installed (my spare)
Controller - I have 24 - 36V spare ready
#2. 2008 eZip Mountain Trailz - 4000+ miles Snow Beast
Immediately replaced 24V controller with 36V from eZip scooter.
Placed 36V 10Ah SLA in toolbox and bolted to rack.
Loved the better speed and torque!
Seemed top heavy and limited range ... so I started recycling laptop cells into 37V 20.8Ah packs.
Turned into my dedicated Winter bike.
Built studded tires for front and eventually got a used carbide studded for rear.
I swap the front tire, dependent on weather! (to save from excessive stud wear)
Shoehorned 33.3V 31.1Ah LiCo laptop cells into oem battery pack!!!
#3. 2008 eZip Trailz 8000+ miles - smooth street tires (My pedal bike)
I pioneered the 16T mod ...
Replaced 20T wheel freewheel with 16T ACS Southpaw and pushed motor speed from 16mph to 20mph.
OEM controller would not support 37V so I built my 1st 7s12p 25.9V 31.2Ah recycled laptop cell battery, in the oem pack.
Later I began building 25.9V 26Ah Laptop LiPo batteries in the oem packs.
Pedal speed came up a bit shy since motor alone was ~22mph with good assist till ~25mph, so I hunted and found the Long-Yih and Epoch DNP 7 speed freewheels with the 11T sprocket. 20mph is a casual ~60 pedal rpm and can push near 30 with a tailwind or slight downgrade.
Implemented a quick disconnect on all motors for quick change.
At about 8000 miles the motor suffered a bearing failure, got replacement bearings, but brush wear is close and replacements require excessive shipping cost, so unit is retired until I find better price or get combined shipping on multiple brush sets.
(Tried wheel-motor-16T freewheel on 37V 2008 MT and easily maintained 27mph and hit 30 mph with aggressive assist)
#4. 2009 eZip Trailz LS (Low Step) - ~8000 miles My Comfort Cruiser
Added big balloon white sidewall tires, suspension post and big comfy seat.
Has the quieter XYD-16 motor and with seat fully lowered it is truly a pleasure for mindless meandering.
I added the 16T mod for 20mph capability.
An oddity, for 2009, it supports 24 - 36V batteries.
Suffered multiple spoke problems till I relaced w/washers.
After a recent rear hub failure, I replaced rear wheel with a 12ga spoked and washered HD eZip rebuild.
Just for fun, I used a lower 22T wheel freewheel, this should provide a substantial torque increase and with my 33.3V pack, ~20mph "legality".
Turned my Comfort Cruiser into my Heavy Hauler ... at least temporarily, will likely swap rear wheel to my Snow Beast ...
(Oh! Whitewalls not recommended with rim brakes! Brake-Aluminum residue is nasty dirty)
#5. 2008 eZip Trailz - Unknown mileage
Front end run over by car.
Needs:
Front fork and wheel. Have nice suspension fork w/disc brake, need to lace on new rim
Rear wheel has broken spoke, will relace with 13ga SS spoke w/washer mod.
Will likely apply 13T motor sprocket mod and new oem 20T wheel freewheel. (graphed as optimal gearing for 30mph @ 44.4V)
Controller - Have 24 - 36V controller but want to replace 50V caps with 63V for possible 44.4V compatibility.
Has low mileage and sturdy components and will rig for sustained high cruising speed (Sustainable 30mph as target)
#6. 2013 eZip Trailz LS - 1800 miles
$308 delivered, not my best bargain, but close.
I began by trying the 13T mod (22-23mph@25.9V) but later relented and tried an 11T mod , for 20mph limit and reduced battery wear and tear.
Suffered broken spokes near 1500 miles so relaced a wheel with a quality hub.
#7. 2010 eZip Trailz - unknown mileage
Abused - left outside, front wheel run over so was replaced with old rusty steel wheel.
Needs:
New front wheel
Brake cables - rusted
Brake pads
Wheel spokes replaced - 13ga SS & washers on hand
New tires - cracked and checked
So ... unless I want to fix them all ... to sell, I will be stuck with eZips for the foreseeable future.
Oh! Also have a "new" 2008 iZip Trailz AL.
I've been saving for when I have my mods perfected.
All components are noticeably better, Aluminum frame front disc brake etc. ...
Might get her spruced up for Spring.
11T mod
25.9V 26Ah (25.92) LiPo battery pack
Schwinn Kevlar belted street tires
Full fenders
Lights etc.
