Summit Plus Full Suspension Folding Fat Tire Electric Bike
Made for Work, Built for Adventure
FOLDABLE FREEDOM FOR EVERY TRIP
Fold. Pack. Go.
When you need to save space for storage or transportation, the Summit Plus folds down to a more compact size, making it easier to fit into garages, apartments, RV storage areas, and compatible vehicle cargo spaces.
With folded dimensions of approximately 40.94" × 22.05" × 28.74", the folding design gives you more flexibility for commuting, road trips, camping, and everyday storage without giving up the comfort and capability of a full-suspension fat-tire eBike.
COMFORT BUILT FOR CHANGING ROADS
Leave the Bumps Behind.
The adjustable front fork and four-bar linkage rear suspension work together to soften bumps and vibration from uneven roads. This helps Summit Plus feel smoother and more controlled across everyday riding conditions.
Lock the front fork for a firmer feel on smooth pavement, or open the suspension when riding over gravel, dirt paths, and rough city streets. You get greater comfort and confidence from start to finish.
PEAK POWER WHEN THE ROAD GETS TOUGH
Climb. Carry. Keep Moving.
The 1800W peak rear hub motor delivers 110N·m of torque and 45%+ hill-climbing capability, providing strong assistance for quick starts, uphill rides, and heavier loads.
Whether you're commuting, carrying cargo, or heading outdoors for the weekend, the responsive motor support helps you maintain momentum when the route becomes more demanding.
MORE GRIP ACROSS MORE SURFACES
Go Wide. Ride Steady.
The 20 × 4.0-inch fat tires create a wider contact area for better grip, balance, and shock absorption. They help the Summit Plus feel stable and controlled when road conditions begin to change.
From pavement and gravel to packed dirt and grass, the wide tires work together with the full suspension system to provide a smoother, more confident ride.
REMOVABLE POWER FOR LONGER DAYS
Ride Farther. Charge Your Way.
The 48V 15Ah battery supports up to 75 miles of pedal-assist range under ideal riding conditions. It gives you more freedom for daily commutes, longer work routes, and weekend adventures.
The removable design lets you charge the battery on or off the bike, making it more convenient to power up at home, in the office, or wherever your next ride begins.
Smooth Rides Start Here
From daily routes to outdoor escapes, Summit Plus is built for riders who need comfort, range, and carrying power in one foldable ride.
Powerful motor support helps you climb hills, carry more, and keep moving with confidence.
20" x 4.0" fat tires and full suspension work together to soak up bumps, giving you a smoother, more stable ride across city streets, gravel roads, dirt paths, and outdoor trails.
Fold it into your vehicle, take it to the trail, and enjoy a smoother ride across gravel roads, forest paths, and open outdoor routes.
Main Features
LCD Display
The LCD display shows key ride information in real time, including speed, battery level, mileage, riding mode, PAS assist level from 1 to 5, and cruise control mode. Whether you need lighter assistance for longer range, stronger support for hills and cargo, or a steadier ride with cruise control, the display helps you monitor your ride at a glance.
Adjustable Front Fork Suspension
The adjustable front fork suspension helps absorb bumps from the road ahead and improves front-end control on rough pavement, gravel paths, and uneven outdoor terrain. Riders can fine-tune the suspension feel for better comfort and stability, making daily commutes, cargo rides, and trail-style adventures smoother and easier to handle.
Four-Bar Linkage Rear Suspension
The four-bar linkage rear suspension allows the rear wheel to move more naturally over bumps and uneven surfaces, adding cushioning and helping the rear of the bike feel more composed during rougher rides, cargo trips, and changing road conditions.
Twist Throttle
The twist throttle delivers instant power with a simple turn of the grip, helping riders start from a stop, move through traffic, climb small hills, or take a break from pedaling when needed. It is especially useful for long delivery routes, cargo rides, and moments when extra support makes the ride easier.
Cadence Sensor Pedal Assist
The cadence sensor pedal assist system detects your pedaling motion and provides motor support as you ride. It helps make starts, hills, long commutes, cargo rides, and outdoor routes easier, while allowing riders to choose different assist levels based on speed, range, and riding comfort.
20" x 4.0" Fat Tires
The 20" x 4.0" fat tires provide a wider contact area for better grip, balance, and shock absorption. They help Summit Plus stay stable on pavement, gravel, dirt paths, grass, and uneven outdoor terrain, making the ride smoother and more controlled.
Shimano 7-Speed Gear Shifter
The Shimano 7-speed gear shifter lets you adjust your pedaling effort for different roads and riding conditions. Use lower gears for hills, heavier loads, or slower riding, and higher gears for smoother cruising on flat roads and open routes.
Front Headlight & Rear Brake Light
The bright front headlight helps illuminate the road ahead during early-morning, evening, and other low-light rides. The rear brake light brightens when you apply the brakes, giving riders and drivers behind you a clearer signal that you're slowing down.

How to Assemble
This short video will show you how to easily assemble your new electric bike. The video provides clear steps and helpful tips to assist you.
Please read our FAQs page to find out more.
Do 4-inch fat tires feel slow on pavement?
Fat tires naturally create more rolling resistance than narrow commuter tires, but they also add cushioning, grip, and a more planted feel over cracked pavement, potholes, gravel, and uneven roads.
The Summit Plus pairs its 20" × 4.0" fat tires with full suspension and motor assistance, making the setup practical for riders who value comfort and mixed-surface capability as much as low rolling resistance. Keeping the tires properly inflated can also help improve rolling efficiency on pavement.
Will I actually get 75 miles in real-world riding?
The Summit Plus can provide up to 75 miles of range under ideal pedal-assist conditions, but real-world range depends on how and where you ride.
Higher speeds, frequent throttle use, steep hills, heavier cargo, colder temperatures, low tire pressure, and higher assist levels can all use more battery energy. For longer rides, moderate pedal assist, proper tire pressure, and appropriate Shimano gearing can help you make more efficient use of the 48V 15Ah battery.
If the Summit Plus folds, is it easy to lift into a car?
Folding makes the Summit Plus more compact—it does not make it lightweight. At approximately 79.4 lbs, the bike may still require careful lifting or assistance when loading it into a vehicle.
The folding design is most useful for reducing the space needed in an SUV, van, RV, garage, or storage area. You can also remove the battery before lifting to reduce some of the weight you need to handle.
Should I use the throttle, pedal assist, or mechanical gears?
They serve different purposes. The Shimano 7-speed drivetrain changes how much effort you put into pedaling, PAS controls how much motor assistance you receive while pedaling, and the twist throttle provides motor assistance without continuous pedaling.
For everyday riding, use a lighter mechanical gear for starts and hills, then shift higher as your speed increases. Pedal assist is generally better suited to longer rides, while the throttle is useful when you want immediate assistance for a start or short section of the ride.
Is full suspension useful if I mostly ride on city streets?
Yes. Full suspension isn't only useful on trails. Potholes, cracked pavement, speed bumps, road joints, and rough neighborhood streets can all transmit vibration through the bike.
The Summit Plus combines an adjustable front fork, four-bar rear suspension, and 20" × 4.0" fat tires, giving the bike multiple layers of cushioning when everyday roads become uneven.
