Full suspension mountain bikes are complicated beasts, with sections of the frame that pivot and a shock absorber to moderate that pivot. These parts help limit the bumps that reach your body and keep your rear tire in contact with the trail across all sorts of terrain and obstacles. The complexity and additional parts, however, boost the costs of full suspension bikes considerably, a situation that only gets worse when you electrify things.

As a result, some of the electric mountain bikes we’ve looked at are either very expensive or make a few too many compromises to bring the price down. Even aiming for middle-of-the-road compromise hardware costs in the area of $5,000.

But there’s one easy way to lower the price considerably: lose the full suspension. The electric “hardtails” from major manufacturers typically cost considerably less than a full suspension bike with similar components. And because the engineering demands are considerably lower than in a full suspension bike, it’s easier for some of the smaller e-bike companies to put together a solid offering.

So over the course of the spring and into the summer, I’ve been testing two hardtail mountain bikes that were recently introduced by e-bike specialists. First up is the Aventon Ramblas.

The hardware

Aventon is one of the larger dedicated e-bike makers and offers a wide range of bikes at competitive prices. Most of them fall into a sort of generic “commuter” category, though; the Ramblas is the first offering from the company made for a specific audience (though it’s also categorized as a commuter option on the company’s website). It’s also the first bike the company is offering above the $2,000 price point. At $2,899, it’s actually more expensive than one of the electric hardtail models being cleared out by Trek, a company that does not have a reputation for affordability.

What do you get for that price? Solid low/mid-range components from SRAM, including its NX Eagle drive train. There’s a dropper seat, a front suspension from RockShox, and Maxxis tires. The fork is coil based, so it doesn’t offer much in the way of adjustment—what you start the ride with is pretty much what you’ll spend the entire ride experiencing, unlike many alternatives that let you firm up the ride for pavement. (It has a rebound adjustment at the bottom of the fork, but the effects are subtle.) Aventon doesn’t list who makes the rims on its website, and there are no external indications of the manufacturer there.

A mid-motor combined with a huge range of gearing ratios makes for a winning combination.

Overall, it’s about what you’d expect from an entry-level offering. I don’t have any concerns about the durability of the components, and their performance was mostly fine. The one thing that did concern me was the plastic cover over the battery, which didn’t fit against the frame snugly and was only held in place by relatively weak contacts at each end. It’s enough to handle some water splashed off the front wheel, but I wouldn’t trust it to protect the battery while fording anything significant.

Saddle and pedals are matters of personal taste, and many people will argue they’re irrelevant because any serious cyclist will want to replace them anyway. But that’s far less likely to be true on the budget end of the scale, so I did most of my riding on what came with the bike. The pedals, while lacking the threatening-looking screws of serious mountain bike offerings, worked out fine when paired with a sticky set of mountain bike shoes, though I felt I had a bit more confidence going over bumps on a ride where I swapped in my clipless pedals.

The saddle, however, was a problem, in part because the frame was a bit too small for my relatively long legs. The saddle has a relatively slick surface that, when combined with my road biking shorts, meant I tended to slide toward the back of the seat over time. A better-fitting frame might have solved this issue (the large version was supposedly rated up to my height, but I clearly should have gone for the XL).

The RockShox forks don't offer much in the way of adjustments, but they work reliably.

Speaking of the frame, Aventon has detailed measurements of the geometry available if those make sense to you. But my experience was that the bike was fairly compact in the seat-to-handlebar dimension, leaving me feeling that I was leaning over the handlebars a bit more than I do in other bikes. It wasn’t uncomfortable; it just felt different.

Urban runaround —

The arrival of e-bikes has blurred the lines between bicycles, mopeds, and scooters. Depending on what country or state you’re in, some e-bikes can legally hit 45 km/hour (28 mph), yet they don’t require a license, registration, or insurance, unlike their competitors. Whether that’s a good or bad thing depends on whether the bike riders in your area ride like lunatics or not.

Regardless of how you feel about the state of things, it’s definitely true that most e-bikes are relatively bike-like compared to mopeds and scooters, lacking things like brake lights, directionals, and other components that make navigating in urban environments a bit safer. Most, but not all. Heybike offers a number of scooter-substitute e-bikes that come with a powered horn, brake lights, directionals, and a zippy motor. As a bonus, they’re foldable. We checked out its latest model, the $1,499 Ranger S.

A foldable heavyweight

Let’s address one thing right away: In our review of the Ranger S’s sibling (the Tyson), we ran into a number of mechanical problems that threatened to make the bike unusable. The only real issue we saw on the Ranger S was a rapidly fluctuating reading of battery capacity. Otherwise, the bike was solid.

Another minor problem we had was with a metal loop that Heybike includes to protect the rear derailleur from damage. Apparently, it served that role during shipping, as it was bent in such a way that it kept the derailleur from reaching the smallest two gear rings. This was pretty easy to spot, and also easy to bend back into its normal position, after which all seven gears were accessible.

The hinge in the center of the frame that allows the bike to fold. The release will only move if the silver metal slider embedded in it is pushed upward from beneath.

The bike’s folding mechanism worked without issue—the frame folds in half so that the front and rear wheels wind up next to each other, and the handlebars fold down to the side. When folded, a different metal loop keeps the front gear ring from resting on the ground.

This is not, however, a “fold it and carry it up the stairs to your apartment” bike. The Ranger S weighs over 32 kg (72 lbs). That’s over 15 kg more than the Gocycle folding bike we reviewed earlier, and it’s enough to make moving it around a challenge. It also lacks any sort of mechanism for holding the bike in a folded position (I’d recommend investing in a bungee cord if you get one), meaning it has a tendency to flop back open as you’re shifting it, adding to the challenge.

This is not to say the folding is pointless. You can definitely store it in a smaller space than many other e-bikes. And it was a snap to lift it into the hatchback I drive, allowing me to take the car in for service without needing to find a place to sit for a few hours. But it doesn’t open up the full range of use cases that an easier-to-manage folding bike would.

When fully folded, the Ranger S is fairly compact but awkwardly heavy.

The upside of the robust construction is that the Ranger S can haul a lot of stuff. The total capacity is listed as 180 kg (400 lbs) between rider and cargo. Heybike offers panniers for the rear rack, with 30 liters of capacity, and you can place up to 13 kg (28 lbs.) in an optional front basket. This isn’t a cargo bike, but it can definitely haul some groceries home, even if you’re a heavy rider.

The drivetrain

The Ranger S is a Class 3 e-bike, meaning it has a maximum speed of 45 km/hour (28 mph). That comes thanks to a 750-watt motor that can hit a peak output of 1,200 W. Heybike rates its 14.4 Ah battery as providing enough juice to provide pedal assist for up to about 90 km (55 miles), but that is presumably at its lowest assist setting. It’s clear that running it on its maximum assist setting burned through the battery far more quickly than that, although the rapidly fluctuating battery meter on the display made it difficult to tell just how much more quickly—or how much further I could go before the battery went flat. Range anxiety joined me for many of my rides.

The motor is tied to a cadence sensor, which registers when you’re turning the pedals and kicks in the assist if you are. Since you have to pedal an otherwise very heavy bike for a bit before the sensor triggers the motor, there’s also a throttle that will take you up to 32 km/hour (20 mph) before cutting out.
