Our take on the S129 Folding Fat-Tire E-Bike

The Narrak S129 is a folding fat-tire electric bike with a 750W rear hub motor (1,100W peak), a 48V 13Ah battery and 4-inch tires. It folds for car, truck or RV transport and carries up to 280 lb on a step-thru or over frame with a front suspension fork. It runs four modes, including throttle and walk assist, and tops out around 28 mph. Against city folders it trades light weight for off-road traction and power; against full-size fat bikes it trades stability for portability.

About the S129 Folding Fat-Tire E-Bike

The S129 is an electric folding fat-tire bike with a foldable step-thru/step-over frame. It folds compact enough to fit in a car or truck. The thick, multi-tooth tires are made for hills, trails, gravel roads and other varied terrain.

A shock-absorbing front fork helps smooth the ride. The cables are routed inside the frame. The bike has a detachable luggage rack and an aluminum saddle, and it supports up to 280 pounds.

A 750W rear-drive motor (1100W peak) and a 48V 13Ah (624Wh) lithium battery power the bike to speeds up to 28 mph. It has four riding modes: Walk Mode, Throttle Mode (up to 28 mph without pedaling), Pedal-Assist Mode and Regular Bicycle Mode for pedaling without assistance. A 7-speed Shimano drivetrain handles gearing, and dual 160mm disc brakes handle stopping. Integrated LED headlight and taillights provide visibility.

Questions and answers

How fast does the S129 go?
The 750W motor peaks at 1,100W and reaches about 28 mph. Throttle-only riding drains the battery fastest.
How far can it go on a charge?
The 48V 13Ah battery is rated at 624Wh. Real range depends on mode, rider weight and terrain, and throttle use or cold weather shortens it.
Can it fit in a car or RV?
Yes. The frame folds and the rear rack detaches, so it stows in a trunk, truck bed or RV storage bay.
How much weight can it carry?
The aluminum frame and saddle are rated for up to 280 lb, including the rider.
What comes in the box?
The bike arrives mostly assembled with the battery, charger and pedals. You fit the front wheel, handlebar and pedals and check the brakes before riding.
Is it good for sand and trails?
The fat tires and rear-drive motor suit beach, gravel and moderate trails. It is not a downhill or jumps bike, and the folding frame flexes under hard pedaling.
Where is the S129 Folding Fat-Tire E-Bike cheapest?
At Narrak E-Bike, for $640.00, as of our latest check.
