Types of e-bikes: which one fits how you ride

The first time I put the Aventon Ramblas on a real climb, its mid-drive gave me what I called an insane amount of torque (Ramblas video, 3:31 to 3:35). Put that same bike on a flat bike path and you’d be paying for suspension you never use. That’s the whole idea of this page. The class tells you how fast the motor helps (classes explained). The type tells you what the bike is built to do, and if you pick the wrong type, good specs won’t save it. A 77 lb fat tire bike is a pain in a third-floor walk-up, and a small-wheeled folder feels skittish on a rutted gravel road.

Here are the six main types, told through the bikes I’ve ridden, with the shopping checks I’d make for each.

The six types at a glance

Weights run from about 40 lb for the ONEBOT S7 folder (18.2 kg) to 93 lb for the Romatlink Dolphin, which I called one of the heaviest bikes I’ve tested (Dolphin video, 8:15).

Commuter

Commuters are built for pavement. You get medium-width tires with a smooth tread, usually fenders and lights, and often a rear rack. Most are Class 2 or Class 3, and a good one is lighter than anything else on this page, which matters when you’re lifting it onto a curb, into a car or up stairs. The Aventon Soltera 2 I rode is a simple city bike: a 350W rear hub that tops out at 20 mph, with regular mechanical disc brakes rather than hydraulics (Soltera 2 video, 2:27). It’s no longer sold new. On Oct 27, 2026, Aventon listed the Soltera 2.5 at $1,199 and the Soltera 3 ADV at $1,499. The Pace 500.3 wasn’t on Aventon’s US store that day, and the Level 3 was $1,699 and sold out.

When I shop for a commuter, I look for fenders and a rack that come with the bike, since add-ons cost extra and often fit worse. I want lights that run off the main battery, a removable battery if I can’t park next to an outlet, and hydraulic brakes if the route has big hills. Skip this type if most of your riding is gravel, sand or snow.

Fat tire

Fat tire bikes use tires about 4 inches wide. They grip on sand, snow and loose gravel, and the big air volume works as extra suspension. They’re also the most popular type I review on the channel. The tradeoffs are weight and rolling drag, which cuts into range. Even so, on my first-gen Aventure I got 41 miles on PAS 5 while climbing hills and riding a lot of off-road, against Aventon’s 45 mile average (Aventure video, 5:28 to 5:33).

The fat tire bikes I’ve ridden split by motor. The Aventure 3 and the Mokwheel Obsidian use rear hub motors, and the Obsidian adds full suspension, which helps a lot on washboard roads. The Aventure M uses the same A100 mid-drive as the Ramblas, as a Class 1 bike at 20 mph (Aventure M video, 5:30 to 5:37), and I said that mid-drive felt more responsive than a hub motor (7:38). On Oct 27, 2026, Aventon listed the Aventure 3 at $1,999 and the Aventure M at $2,899, both in stock, and Mokwheel had the Obsidian at $1,799.99. There’s a longer breakdown in best fat tire e-bike.

Before you buy one, check the tire pressure range, because lower pressure on sand makes a huge difference. See whether a rack and fenders come with it, and measure where you’ll park, since these bikes are wide and heavy. Skip this type if you need to lift the bike often or you ride only on smooth pavement.

Cargo

Cargo bikes carry kids, groceries or work gear, either on a long rear deck (a longtail) or in a front box. Almost all are Class 2, because a throttle makes loaded starts so much easier, and these are the bikes most likely to replace car trips. The Aventon Abound I rode carries 440 lb (Abound video, 1:19), but I warned that it can creep up to just under $3,000 once you add accessories (7:52). The original Abound is no longer on Aventon’s store. On Oct 27, 2026, its successors were the Abound LR at $1,999 and the shorter Abound SR at $1,899, which I cover in the passenger seat guide. The RadWagon 4 carries up to 350 lb (RadWagon video, 3:12 to 3:16), and Rad listed it at $1,799 but sold out that day. The MOD Easy SideCar is the odd one: it puts a passenger beside you, and its motor pulled the bike, sidecar and kids up a hill easily (SideCar video, 3:04). MOD listed the Easy SideCar 3 at $3,899, in stock.

Compare the total payload with you plus your heaviest load, and check the rear rack rating separately. Price in the passenger accessories you’ll actually need, like a seat pad, running boards and a rear enclosure. You want a kickstand that holds the bike steady while kids climb on (the SideCar’s didn’t do much with the sidecar attached, 4:36), and a ground-level place to park. Skip this type if you have no ground-floor storage or you rarely carry more than a backpack.

Folding

Folding e-bikes hinge at the frame and usually the handlebar stem, so they fit in a car trunk, under a desk or on a train. To make them small, makers use 16 to 20 inch wheels. Smaller wheels turn quickly, which feels twitchy at speed and harsher over potholes. They’re great for RVs, boats, apartments and commutes that include a train or bus.

Check the folded size and weight first, because a folder you can’t lift into your trunk fails at its one job. Make sure the fold latches feel solid with no play, and see whether you can charge the battery outside the bike. Skip this type if your rides are long, fast or rough. My best folding fat tire e-bike guide covers the ones I’ve ridden.

Mountain (eMTB)

Electric mountain bikes have trail geometry, real suspension and knobby tires. The good ones use a mid-drive with a torque sensor, so the assist matches how hard you pedal and technical climbs feel controlled instead of jerky. The Ramblas was Aventon’s first mid-drive, a hardtail with a RockShox 35 fork and no rear suspension (Ramblas video, 0:40 to 0:52). It runs a 12-speed SRAM Eagle (3:31) and Maxxis Rekon 29 x 2.4 tires (4:09). Aventon now sells the Ramblas ADV at $2,899, and lists it at 54 lb with 100 Nm and a 708 Wh battery. I haven’t ridden the ADV.

Class 1 matters here, because it’s the class trail managers most often allow. Several state laws, including Washington, Minnesota, Maryland, Virginia and Texas, let local governments or land agencies set their own rules for paths and trails, so check the trail system’s rules, not just your state’s. Skip this type if you ride only on pavement.

Moped-style

Moped-style bikes look like small motorcycles, with a long bench seat, fat tires and often foot pegs, and they’re popular with teens. Most states define an e-bike as having working pedals and a motor of 750W or less, with assist cutting out at 20 or 28 mph (Michigan’s definition is typical). Plenty of moped-style bikes sold online go past those limits. If a bike doesn’t fit a class, it may legally be a moped or a motor vehicle, with licensing and registration to match.

The Fahrbike Roadster 73 was $899 for Orange or Blue and $1,399 for Dark Green on Oct 27, 2026, all sold out. The Ailife X20B I rode is no longer listed, so if you want a moped-style bike I’ve filmed, look at the MACFOX X7 instead. Look for a class sticker on the frame (Arizona, Florida, Ohio and Virginia are among the states that require one), the real motor rating and top speed rather than “up to” numbers, and pedals you can actually use. Skip this type if you want to pedal for exercise, or if it’s for a rider too young for a license. The parents’ guide covers that.

Hub motor or mid-drive?

A hub motor sits in the rear (sometimes front) wheel and feels like a push from behind. It’s cheaper and fine on moderate hills. A mid-drive sits at the cranks and feels like stronger legs, and it’s better on steep climbs because it works through your gears. The Aventure 3, Abound, RadWagon 4 and Obsidian I rode are hub drives. The Ramblas and Aventure M are mid-drives, and the Aventure M even shifts for you by measuring the torque you put into the cranks (Aventure M video, 2:40).

How I’d pick

Start with the ride you’ll do most often, not the one you’ll do once a year. That points you to a type. Then pick a class from classes explained and your state’s rules, check the weight against where you’ll store the bike, and only then compare specs. My reviews list tested range wherever I measured it.
