Quiet Motor That Outperforms ATVs

ATVs announce your presence long before you see the game. The Jetty 4.0's 350W rear-hub brushless motor operates so quietly that nobody will know you're riding an electric bike — no engine rumble, no exhaust smell, no trail damage. This design delivers silent ride access that gets you deeper without spooking anything. At just 40 lbs, you cover ground an ATV simply cannot reach, through narrow trails and quiet paths where the best spots live. The throttle and pedal assist let you control your speed precisely, so you move at nature's pace instead of fighting a machine.

Folds to Half Size in Seconds

The Jetty 4.0 folds to 50% its size, transforming from full ride to compact transport in moments. At 40 lbs, this vetted frame fits in apartments, car trunks, closets, and even boats — no rack, no trailer, no hassle. Unlike bulky e-bikes that demand dedicated parking, the Jetty disappears when you need it to and reappears when the day calls for riding. The internal gearing system protects against damage from falls, so this investment holds up whether you're tossing it in a truck bed or stowing it below deck. Third-generation refinement means the folding mechanism is proven, not experimental.

Glow-in-the-Dark Frame for Low-Light Rides

The entire frame glows in the dark — not a sticker, not a strip, the whole frame — so you stay visible when light conditions drop. Combined with included head and taillights, a bell, reflective tires, and fenders, this bike is built for riders who don't quit when the sun does. The Tektro mechanical disc braking system stops you on a dime in any weather, giving you control when wet roads or steep descents demand it. The 36V 10.4Ah battery and 30-45 mile range mean your low-light rides won't end with a walk home. This is craftsmanship that accounts for real riding conditions, not showroom floors.

“I bought this for commuting to my hunting lease and didn't expect much from a folder. The glow frame caught my eye, but the quiet motor is what sold me — rode right past a doe at 15 yards and she didn't flinch. Folds down small enough to fit behind my truck seat. Third month in, no issues.”

Frequently Asked Questions

The Jetty 4.0 ships in a box partially assembled. You will need to attach the pedals, handlebars, seat, and front wheel. Basic tools are required. Assembly typically takes 30 to 60 minutes. No special mechanical skills are needed, but follow the included manual step by step.
The Jetty 4.0 is designed for riders from about 5'0" to 6'2" tall. It has a maximum weight capacity of 275 lbs, which includes rider and cargo. Always stay within this limit for safe operation and to protect the frame, battery, and motor.
The battery takes approximately 4–6 hours for a full charge. It is removable, so you can charge it on or off the bike. This makes it convenient for apartment dwellers or anyone who cannot bring the entire bike indoors.
Routine maintenance includes checking tire pressure, lubricating the chain monthly, and inspecting brake pads for wear. The internal gear system is low-maintenance but should be serviced by a professional annually. Keep battery contacts clean and store the battery at room temperature when not in use.
The Jetty 4.0 comes with a 2-year warranty covering the frame, battery, and motor. For returns, contact Fifield directly within 30 days of delivery. The bike must be in original condition and packaging. Shipping costs for returns are the customer's responsibility.
The 350W motor and 36V battery provide enough power for gentle inclines and packed dirt or gravel paths, but it is not built for extreme off-road or steep, loose terrain. It excels on paved roads, bike paths, and light trails. For aggressive off-roading, consider a dedicated mountain e-bike.
This folding e-bike is ideal for urban commuters, apartment dwellers, RV or boat owners, and anyone who needs a portable, space-saving electric bike. Its 40-lb weight and compact fold make it easy to carry onto public transit or store in a closet. It also suits casual riders looking for a reliable, low-maintenance e-bike.
