The Aventon Pace 4 Step-Through is the bike that replaced the Pace 500.3, the step through cruiser I rode for several weeks. I haven’t ridden the Pace 4. What follows comes from Aventon’s official product page, checked on Oct 27, 2026, compared against the Aventon bikes I have filmed. Aventon gave it a bigger battery, connected features and a suspension seatpost. As of Oct 27, 2026, though, Aventon no longer has it for sale.
Should you buy one?
Not new from Aventon. As of Oct 27, 2026, Aventon’s US site still shows the Pace 4 Step-Through at $1,599, but all six versions (Regular and Large in Blue Steel, Mica and Flint) are listed as unavailable. The only ways to get one are leftover dealer stock or a used bike.
If you want a step through you can order today, these are the current options:
- Aventon Pace 5 REC Step-Through, $1,799 and available on aventon.com as of Oct 27, 2026. It’s the bike Aventon sells in the Pace 4’s place. I haven’t ridden it.
- Velotric Discover 3, $1,999 and available as of Oct 27, 2026, with a 730Wh battery, an air fork and a step through frame. I haven’t ridden it either.
- Velotric Discover 2, $1,499 and available as of Oct 27, 2026. I rode this one, about 30 miles on gravel and paved paths.
If you do find a Pace 4, compare the asking price with the $1,799 Pace 5 before you buy.
What changed from the Pace 500.3 I rode
The biggest change is the battery. The Pace 500.3 I filmed had a 48V 12.8Ah (614Wh) pack. Aventon lists the Pace 4 at 36V 20Ah, which is 733Wh, with LG 21700 cells, and rates it for up to 70 miles for a 165 lb rider in Eco. That’s about 19% more energy than the 500.3, by my math. The battery is keyless, weighs 8.7 lb and charges in about 5 hours on the included 42V 4A charger. Aventon says it’s the same battery used in the Abound SR and LR, Level 3 and Aventure 3, so if you already own one of those, the packs can swap. I filmed the Abound SR, Abound LR and Level 3.
The motor is a 36V 500W rear hub with 60 Nm and a 24A controller. Aventon also lists a Boost Mode that gives 120% power for 30 seconds. On the Pace 500.3, at about 200 lb, I had no trouble on the gentle inclines of the trail I filmed on. I can’t say how the Pace 4’s motor compares without riding it.
The comfort change is a 50mm travel suspension seatpost. The fork is still rigid aluminum, like the 500.3’s. On the concrete trail where I filmed the 500.3, I found that not having suspension didn’t make much difference. The seatpost is there for rougher pavement.
The bike also got heavier. Aventon lists the Pace 4 Step-Through at 58.2 lb, against 54 lb for the 500.3, with the same 300 lb total weight limit.
The sensor question
Aventon’s own page contradicts itself here. The spec table lists a “Double Sided Bottom Bracket Torque Sensor.” The marketing copy describes a Sensor Switch that lets you choose between torque and cadence feel, and says there are 3 customizable levels of pedal assist. I couldn’t confirm which is accurate from the page, so if the sensor matters to you, ask Aventon or the dealer.
For what it’s worth, the torque sensor was one of the things I liked most about the Pace 500.3. It felt very natural, with the assist following how hard I pressed the pedals.
Speed and class
Aventon lists a 28 mph max and calls the Pace 4 a Class 2 bike that can be converted to Class 3. Out of the box, that means a 20 mph limit on throttle and pedal assist. Where you can legally ride faster depends on your state; see my e-bike laws by state and Class 2 vs Class 3 pages.
Brakes and drivetrain
The brakes are Tektro hydraulic discs with 180mm rotors and motor cutoff switches, which stop the motor as soon as you touch a lever. The drivetrain is a Shimano Altus 8 speed with a 12-32T cassette, a 48T chainring and 170mm cranks. The 500.3 I rode also had hydraulics; its shifter, the thumb and index finger style, was one I really liked.
The tires are 27.5 x 2.1 in, and the bar is a 720mm BMX style bar on a 50mm stem.
Fit
Aventon sizes the Step-Through in two frames. The Regular fits riders 4’11” to 5’7” and the Large fits 5’7” to 6’1”. The standover height is 430mm, and the wheelbase is 1085mm on the Regular and 1110mm on the Large. On the 500.3, my wife and I both rode the same Regular frame, and the stem and seat adjustment made that work. Aventon’s height ranges for the Pace 4 split that span into two sizes, so check yours before buying.
The connected features
This is where the Pace 4 is a new generation. Aventon lists a BC147 display, its Ride Tune app tuning, and a 4G and GPS module with the first year free, then a paid subscription. The connected features include geofencing, remote shutdown, an alarm, a rear wheel E-lock, a Hold Mode, a startup password and Apple Watch support. There’s also cruise control and over the air updates.
If the 4G subscription lapses after the first year, check with Aventon which of those keep working.
Safety ratings
Aventon lists UL 2849 for the electrical system and UL 2271 for the battery. Its FAQ gives an IPX5 rating, a step up from the IPX4 Aventon Canada listed for the Pace 500.3.
How it compares with Aventon bikes I’ve filmed
Against the Pace 500.3: the Pace 4 has more battery, a suspension seatpost and connected theft features, and weighs about 4 lb more. The 500.3 is discontinued and only available used.
Against the Level 3: the Level 3 shares the same battery and is Aventon’s commuter, sold in high step and step through frames. Aventon listed it as discontinued when I checked on Oct 24, 2026, so like the Pace 4, it’s a used or leftover stock buy.
Against the Abound SR and Abound LR: those are cargo bikes that use the same battery. If you want to carry a kid or groceries, they’re the better fit. If you just want a bike for paths and errands, the Pace is the smaller, lighter bike to live with.
Warranty
Aventon lists a 2 year warranty. Check the return terms on Aventon’s site or with your dealer before you buy, since leftover stock may be sold under different terms.
FAQ
Have I ridden the Pace 4?
No. I rode the Pace 500.3, the model it replaced. This page uses Aventon’s official specs, checked on Oct 27, 2026.
Can I still buy one new from Aventon?
No. As of Oct 27, 2026, all six variants were listed as unavailable on Aventon’s US site. The Pace 5 REC Step-Through was available at $1,799.
Does it have a torque sensor?
Aventon’s spec table says yes, but its marketing copy describes a switch between torque and cadence feel. Ask before you buy.
How far does it go?
Aventon rates it for up to 70 miles, for a 165 lb rider in Eco. Heavier riders, hills, cold and higher assist will cut that.
Pros and cons (from the specs)
Pros: 733Wh battery shared with other Aventons; hydraulic brakes; suspension seatpost; 4G and GPS theft features; two frame sizes.
Cons: unavailable new from Aventon as of Oct 27, 2026; Aventon’s page contradicts itself on the sensor; rigid fork; 4G needs a paid plan after year one; heavier than the 500.3.
Who it’s for
The Pace 4 makes sense for someone who wants an easy to mount cruiser for paved paths and errands, values theft tracking, and can find leftover or used stock for less than the Pace 5. If you already own a Level 3, Abound or Aventure 3, the shared battery is a bonus.
Price
$1,599 list on Aventon’s US site as of Oct 27, 2026, but every variant is unavailable, so you can’t buy it new from Aventon. Current alternatives as of the same date: the Pace 5 REC Step-Through at $1,799, the Velotric Discover 3 at $1,999 and the Velotric Discover 2 at $1,499.
