The 20mph USA "legal" eBike speed begins to look more "reasonable" than it did originally?Originally Posted by DrkAngel
I have multiple "compliant" eBikes:
2009 eZip Trailz LS (Low Step)
No pretenses, 20mph limit on a big tired, low slung big suspension seat, full upright position.
Typically I "cruise" at 15mph and "meander" even slower.
Designed for motor only, but I do apply some assist getting up to speed and on hills ...
Dumped the 24V 10Ah SLA batteries and packed 25.9V 25.92Ah LiPo into the oem eZip battery case.
The battery upgrade, combined with the 16T upgrade provides a reasonable ~20mph.
2008 eZip Trailz
Designed to commute at a sustained 20mph.
29.6V 31.2Ah homemade Li-ion battery pack.
16T upgraded drive gear.
Smaller, higher pressure, Kevlar belted, low RR tires.
Proper pedaling position seat.
Designed for continuous pedal assist, motor only 20mph+, reasonable pedal assist provides extended range or a sustainable 25mph.
Safety gear includes reflective tires, strobe headlight tail and turn signals, (mirror is mounted on helmet).
2008 eZip Mountain Trailz
Winter only, designed to mush through slush, snow and ice.
OEM 20T gearing but upgraded from 24V SLA to 33.3V 31.2Ah Li-ion for a ~20mph capability with a substantial torque increase. (1st upgrade 37V 20.8Ah Li-ion battery replaced for better durability and 20mph legality)
Homemade studded tires ... front tire quick swaps between mountain tread and sheet metal screwed mountain tire, dependent on road conditions. Rear tire is a used carbide studded tire, drive wheel wears steel studs too quickly. Home made studded provides better traction than the carbide.
I do assist for extra umph, when needed,
When really icy-nasty ... I lower seat and ski my feet.
Might have gone overboard with this one ...
Then I went way too far ...
So 20mph is OK by me ... though I might push the limits.
