Rattan LF Ultra — Product Description
The Rattan LF Ultra is a long-range folding fat tire electric bike built for riders who want serious distance, two-up capability, and the convenience of a folding frame — a strong fit for commuters, campers, RV and boat owners, and anyone who wants one bike that does a lot. Here's what to know as you decide whether it fits how you'll use it.
Long range and big battery. The LF Ultra's standout feature is its 48V 40.5Ah battery — one of the largest in its class — supporting up to 120 miles of range per charge. That's enough for multi-day trips, long commutes, or riding for days between charges. As with any e-bike, real range depends on rider and cargo weight, terrain, throttle use, and assist level; expect the upper end with steady pedal assist on flat terrain and less with heavy throttle use, two riders, or hills. A full recharge takes 7–8 hours with the included 4.5A charger.
Power. The LF Ultra runs a 1000W 48V brushless rear hub motor with up to 1800W peak output — strong, confident power for getting a loaded bike moving, carrying a passenger, and handling moderate hills. A half-twist throttle and five levels of pedal assist let you choose how much help you want.
Two-seater capability. The LF Ultra is built and rated to carry a passenger, with a rear seat, foldable footpegs, and a 400 lb total payload capacity. That makes it a practical companion bike for couples, errands with a passenger, or family use — just confirm both riders stay within the rated payload and ride within the bike's design limits.
Folding, accessible design. The frame folds for storage and transport — easy to fit in a car trunk, RV bay, or closet — and comes in both step-through and high-step frame options, so you can pick the style that suits your height and how you ride. The 20" x 4.0" CST fat tires add stability, comfort, and grip across pavement, gravel, and light off-road, and include a puncture-resistant liner.
Stopping and drivetrain. Dual hydraulic disc brakes provide strong, consistent stopping power — important on a heavier bike that may carry two riders and cargo. The Shimano 7-speed drivetrain lets you keep a comfortable pedaling cadence across flats and hills. Integrated front and rear lights, including a brake-light indicator, come standard for road-ready visibility.
Riding class and where you can ride. The LF Ultra is a high-performance e-bike capable of speeds above the standard Class 3 limit. Many areas restrict where higher-speed e-bikes can be ridden — often limiting them to private property or specific roadways rather than bike paths and multi-use trails. Check your state and local e-bike laws before riding to understand where this bike is permitted.
Safety. The LF Ultra is UL listed for e-bike and battery safety, with a battery management system that helps maintain battery longevity — an important consideration for a bike often stored and charged indoors.
Who it's best for. The LF Ultra suits riders who want maximum range, two-up carrying capability, and folding convenience in one bike — ideal for camping, RV travel, long commutes, and shared rides — and who value distance and versatility over lightweight handling.
