"Most folding bikes ask you to give something up. Speed, brakes, comfort, pick one. This one folds into a trunk and still tops out at 28 mph on hydraulic discs."
The Buzz Centris 2 is a folding fat tire electric bike built for people who are short on storage and long on places to be. The aluminum frame folds down for a car trunk, an RV bay, a boat locker, or the corner of an apartment. The 500W rear hub motor puts out 65Nm and carries you to a 28 mph top speed, which is quick for anything that folds.
It also stops like a bike that costs more. Hydraulic disc brakes front and rear, not the mechanical calipers most folders ship with. Add 20 by 4 inch fat tires, 60mm of front suspension travel, and a step through frame you can get on without a ceremony, and you have a bike that handles broken pavement and gravel shoulders as happily as a bike lane.
"Look at what usually gets cut on a folding e-bike at this price. It is almost always the brakes. Mechanical discs, because they are cheap and nobody reads the spec sheet. The Centris 2 ships hydraulic front and rear on a bike that does 28 mph. That pairing is the whole story here, because stopping power should scale with top speed and on most folders it does not."
BUILT FOR RIDERS WHO
- You do not have room to store a full size bike and refuse to make that your problem
- You travel with an RV, a boat, or a small car and want the bike to come along
- You want real stopping power, not the mechanical brakes most folding bikes settle for
- You ride broken pavement, gravel shoulders, and curb cuts on the way to work
- You want to get on and off without swinging a leg over a high top tube
A FOLDING FRAME THAT DOES NOT RIDE LIKE ONE
Aluminum, Step Through, Genuinely Portable
The frame is aluminum and folds for storage and transport, which is the entire point of a bike like this. What is less common is that it does not feel like a compromise once unfolded. The 20 by 4 inch fat tires put a wide contact patch on the road and soak up the surfaces a narrow tire would rattle across.
A front suspension fork with 60mm of travel handles the rest. Between the tire volume and the fork, potholes and expansion joints stop being events. The step through layout means you can mount and dismount in traffic without hopping, which matters more than people expect on a heavier bike.
HYDRAULIC BRAKES ON A BIKE THAT DOES 28
Stopping Power Scaled To The Speed
A 500W rear hub motor producing 65Nm of torque takes the Centris 2 to a top speed of 28 mph, with five levels of pedal assist and a throttle for when you would rather not pedal at all. That is genuinely fast, and it is exactly why the brakes matter.
Front and rear hydraulic disc brakes give you more stopping power with less hand force than the mechanical discs typically found at this price. The 48V 10.4Ah battery covers up to 40 miles per charge and refills in 4 to 6 hours, and the LCD display keeps speed, assist level, and battery in view.
KEY FEATURES
28 MPH Top Speed
A 500W rear hub motor with 65Nm of torque. Quick enough to keep pace with city traffic instead of hugging the curb.
Hydraulic Disc Brakes
Front and rear hydraulics, not the mechanical calipers most folding bikes ship with. More stopping power, less hand effort.
Folds For Storage
Aluminum folding frame for a car trunk, an RV bay, or an apartment corner. No bike rack required.
20 x 4 Fat Tires
A wide contact patch that shrugs off broken pavement, gravel shoulders, and curb cuts.
60mm Front Suspension
A suspension fork that takes the hit before you do. Potholes stop being events.
Step Through Frame
Get on and off without swinging a leg over a top tube. Easier in traffic, easier when loaded.
WHY THIS BUILD MATTERS
Brakes Scaled To The Speed
Plenty of bikes hit 28 mph. Far fewer at this price give you hydraulic discs to slow down with. That pairing is the point.
Storage Stops Being The Blocker
The most common reason people skip an e-bike is having nowhere to put it. A folding aluminum frame removes the objection entirely.
Fat Tires Plus Suspension
Small wheels usually mean a harsh ride. Four inches of tire and 60mm of travel is what keeps this one comfortable.

How fast does the Buzz Centris 2 go?
Top speed is 28 mph. The 500W rear hub motor delivers 65Nm of torque through five levels of pedal assist, and there is a throttle for when you would rather not pedal. Check your local rules, since a 28 mph e-bike is classed differently than a 20 mph one in many states.
What kind of brakes does the Centris 2 have?
Hydraulic disc brakes front and rear. That is a step up from the mechanical discs most folding e-bikes come with at this price. They need less hand force and hold up better on long or wet descents.
How far can it go on a charge?
Up to 40 miles on the 48V 10.4Ah battery. Real range depends on assist level, rider weight, terrain, and how much you use the throttle. A full recharge takes 4 to 6 hours.
How small does the Centris 2 fold?
The aluminum frame folds for storage in a car trunk, an RV storage bay, a boat, or a closet. Assembled it weighs 71.33 lbs, so think of it as folding for storage and transport rather than for carrying by hand.
Who does the Centris 2 fit?
Buzz lists it for riders roughly 5'2" to 6'3", with a payload capacity up to 300 lbs including the rider and any cargo. The step through frame makes mounting easier across that whole range.
Is the battery UL certified?
Yes. Buzz e-bikes are tested and certified to the UL 2849 standard, which covers the complete electrical system rather than the battery cells alone.
