Lightweight

Nearly 20 lbs lighter than the competition

The Lectric XP weighs 64 lbs. The Rad Power weighs 62 lbs. The Jetty 4.0 weighs 45 lbs — light enough to carry up four flights of stairs with one hand, lift into an Uber trunk, or bring inside instead of locking up outside.

45lbs

vs. 62–65 lbs for competitors

Mag wheels. No spokes. No flats.

Zero maintenance

Mag wheels. No spokes. No flats.

Most bikes — even expensive ones — use spoked wheels that go out of true and break under stress. The Jetty 4.0 uses cast magnesium alloy wheels with no spokes to break or true. Ever.

questions?

Everything about the Jetty 4.0, answered.

Yes. Folded, the Jetty 4.0 fits easily in the trunk of most sedans and SUVs. At 45 lbs it's light enough to lift in without help — no van needed, no awkward driver negotiations.

The Jetty 4.0 is carry-on friendly by size. Airline battery policies vary, so always check before flying. Most carriers allow batteries under 160Wh in carry-on baggage.

A full charge takes approximately 5–8 hours from empty using the included charger. Any standard wall outlet works. Most daily riders just plug in overnight.

Up to 60 miles on a single charge under ideal conditions. Terrain, rider weight, and assist level all affect range. Most commuters riding 5–10 miles a day charge once or twice a week.

Yes. The Bafang 350W motor paired with the 8-speed drivetrain handles moderate hills comfortably. For steeper climbs, drop a gear and raise the assist level.

Most riders fold or unfold in under 15 seconds after the first few tries. The 3-step fold is completely tool-free.

The Jetty 4.0 arrives ~85% assembled. Handlebars, front wheel, and pedals attach in 20–30 minutes with basic tools. A guide and video walkthrough are included in the box.

2-year warranty covering manufacturing defects on the frame, motor, and battery. US-based support responds within 1 business day. Wear items are not covered.

Free shipping to the contiguous US, arriving within 5–10 business days. Tracking info is emailed when your order ships.

Yes. We offer a 15-day return window for bikes in original condition. Contact support to initiate a return and receive a prepaid shipping label. Refunds process within 5–7 business days.

The 2-year warranty is tied to the original purchaser and is not transferable. The new owner can purchase an extended service plan through Fifield's support team.
