The Harley Serial 1 Bash/MTN
Built for terrain that would end a commuter bike's motor in a season. This range covers the all terrain electric bike on fat tyres, purpose-built hunting rigs with serious payload, and at the top a small number of bikes that exist because someone wanted to build them. Prices run from $1,499 to $19,300, which is the widest spread on the site. This one runs Brose S Mag mid-drive, paired with a 529 Wh battery for up to 153 km of real-world range.
Single-speed freewheel; Gates Carbon Drive belt; weight for size L
