The X1S is the bike the rest of the Macfox range grew out of: 500 W nominal, a 20 mph Class 2 ceiling, up to 28 miles of range, and a deliberately plain moped silhouette — for $1,399. It is the most-modified Macfox for a reason. Macfox’s one caution, and ours: leave the electronic control system alone.

Why the plain one is the popular one
The X1S styling is deliberately unfussy: a clean moped silhouette with nothing on it that fights what you do to it afterwards. Macfox leans into that — the frame is high-strength carbon steel with reinforced rear wheel supports, because the factory knows exactly how these get used. The result is the platform owners personalize most: seats, racks, lights, cosmetics, and this store carries 33 X1S-fit parts in its own collection, more than any other Macfox platform. Start with the six upgrades that matter on a daily commuter and a visibility setup.
Macfox’s caution, and ours: leave the electronic control system alone. Controller and firmware tampering voids the 2-year warranty and can push the bike out of Class 2 — which is the legal status that lets you ride it without a license in the first place.
Range, honestly
The 48V 10.4Ah pack is the smallest number on the sheet, and it is the honest trade at this price: up to 28 miles is a real daily-commute figure, not a weekend-tour one. A second battery doubles it to 56, and the dual-battery bike is $1,698; note that Macfox ships the second pack separately and that its UL 2271 battery certification covers the single-pack configuration only. If your round trip regularly clears 20 miles, that is the argument for the X2 Pro and its 960 Wh pack instead.
The limited edition
The X1S x Bs.zay is a co-branded limited edition on the same platform — a pearl-white, pearl-powder finish with a shield-shaped LED headlight and gold chain detailing, at the same $1,399. Underneath it is a standard X1S.
Verdict
As a first e-bike, a campus bike, or a project base, the X1S is the easiest entry into the Macfox line: simple, legal everywhere a bicycle is, and built expecting you to make it yours.
Class 2, 20 mph, no unlock: legal as a bicycle in most states. 65 lb, 220 lb rider limit, 33-inch seat, riders from 5'3": the lightest full-size Macfox. 500 Wh, up to 28 miles, or 56 miles and $1,698 with the second pack. Hydraulic discs, UL 2849, 2-year warranty. The most-supported Macfox platform: 33 parts on this store. Ships free; bike returns are 14 days with a 25% restocking fee. Compare it to the X7, M16 and X2 Pro in our Macfox lineup guide.
