*Cash only. Serious inquirers note that I have added a realistic, in-depth written review by someone who owned the bike for a while. It's the last image in the set.
What follows is this temporary owner's description (unboxed in 2025, ridden once to the bike shop):
The Serial 1 brand name is a reference to the first Harley Davidson motorbike called the Serial Number One, which was a pedal-start moped. The brand is actually a spinoff from Harley Davidson, and they operate independently.
Serial 1 made this first generation RUSH/CTY-Speed electric bicycle to be sold at Harley-Davidson dealerships for $5599!
They lowered it to $4999 at some point, and even let Best Buy sell some for less than that.
The Gen 2 version is now promoted on Serial 1's website for a saner $3499 (without the Harley insignia), but I've been watching it for more than a year now and it has yet to be available (in pre-order status for freakin' ever?)
They are, however, still selling Gen 1 compatible parts online, including replacement batteries, directly to consumers. www.Serial1.com
This fine e-bike has a potent (90Nm) yet whisper quiet Brose TF Magnesium motor (ironic for a Harley!)
with varying assist levels to help you get back into shape at PAS speeds of up to 28mph!
It sports an efficient German 706Wh battery
that'll last for hours if used and cared for properly.
And the reliable 10k mile Gates Carbon belt drive
means no more noisy, messy chains!
Enviolo's AUTOMATiQ CVT auto-shifting keeps you in
the correct riding cadence at all speeds and inclines.
(It's adjustable with a wide gearing range for climbing,
cruising and/or getting there yesterday)
If I was a commuter I'd keep it, but my disabilities had other ideas.
