I began by trying the 13T mod but later relented and tried an 11T mod, for 20mph limit and reduced battery wear and tear. $308 delivered, not my best bargain, but close. Has low mileage and sturdy components and will rig for sustained high cruising speed (Sustainable 30mph as target) (graphed as optimal gearing for 30mph 44.4V)Ĭontroller - Have 24 - 36V controller but want to replace 50V caps with 63V for possible 44.4V compatibility. Will likely apply 13T motor sprocket mod and new oem 20T wheel freewheel. Rear wheel has broken spoke, will relace with 13ga SS spoke w/washer mod. Have nice suspension fork w/disc brake, need to lace on new rim (Oh! Whitewalls not recommended with rim brakes! Brake-Aluminum residue is nasty dirty)įront fork and wheel. at least temporarily, will likely swap rear wheel to my Snow Beast. Turned my Comfort Cruiser into my Heavy Hauler. 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". Suffered multiple spoke problems till I relaced w/washers.Īfter a recent rear hub failure, I replaced rear wheel with a 12ga spoked and washered HD eZip rebuild. I added the 16T mod for 20mph capability.Īn oddity, for 2009, it supports 24 - 36V batteries.
Has the quieter XYD-16 motor and with seat fully lowered it is truly a pleasure for mindless meandering. 2009 eZip Trailz LS (Low Step) - ~8000 miles My Comfort CruiserĪdded big balloon white sidewall tires, suspension post and big comfy seat. (Tried wheel-motor-16T freewheel on 37V 2008 MT and easily maintained 27mph and hit 30 mph with aggressive assist) Implemented a quick disconnect on all motors for quick change.Īt 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. 20mph is a casual ~60 pedal rpm and can push near 30 with a tailwind or slight downgrade. 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. Later I began building 25.9V 26Ah Laptop LiPo batteries in the oem packs. OEM controller would not support 37V so I built my 1st 7s12p 25.9V 31.2Ah recycled laptop cell battery, in the oem pack. Replaced 20T wheel freewheel with 16T ACS Southpaw and pushed motor speed from 16mph to 20mph.
2008 eZip Trailz 8000+ miles - smooth street tires (My pedal bike) Shoehorned 33.3V 31.1Ah LiCo laptop cells into oem battery pack!!! I swap the front tire, dependent on weather! (to save from excessive stud wear) so I started recycling laptop cells into 37V 20.8Ah packs.īuilt studded tires for front and eventually got a used carbide studded for rear. Placed 36V 10Ah SLA in toolbox and bolted to rack. Immediately replaced 24V controller with 36V from eZip scooter. 2008 eZip Mountain Trailz - 4000+ miles Snow Beast
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. Then tried 20s1p D cell 6Ah NiCd, then 20s2p, then swapped to 36V SLA. #s 1, 5 and 7 in need of some degree of repair #s 2, 3, 4 and 6 in good running condition Neighbor gave up on his 2010 Trailz so I gave him $73 for it! 2013 Trailz LS got listed (accidentally?) at $308. Neighbor got his eZip Trailz run over by car, front wheel and fork damage, got new 2010 eZip Trailz so I gave him $50 for another 2008 Trailz.Ħ. Too cheap to pass up! - ~$225 deliveredĥ. Couple years later there was a "new, minus battery", 2009 eZip Trailz LS. about $125 after I sold the battery & chargerĤ. About Christmas time there was an absolute bargain on a 2008 eZip Trailz. Caught a 2nd on sale a couple months later. <$300 delivered (don't remember exactly. Got my 1st eZip Mountain Trailz back in 2008.
