How Do the Aventon Level 4 and Abound Versions Differ, and Which Family Fits Your Ride?

Manufacturer, retailer and public-agency sources · 2026-09-24 · no ratings, no road tests

Summary

Aventon's menu files its bikes by use, with Level as the commuter, Pace the cruiser, Soltera the lightweight city bike, Aventure the fat-tire all-terrain bike, Abound the cargo bike, and Current and Ramblas the mountain bikes. The harder choices sit inside those families, where the Level 4 comes with a hub motor or a mid-drive and the Abound comes in a short and a long version. Many older reviews cover the Level 3, which is a different bike from either Level 4.

Level 4 REC or Level 4 ADV

The two Level 4 models run on different drive systems, a hub motor on the REC and a mid-drive on the ADV.

	Level 4 REC	Level 4 ADV
Motor	Hub motor, 80 Nm (96 Nm in Boost), 1,188W peak (1,440W in Boost)	Aventon Ultro S mid-drive, 100 Nm, 750W peak
Class as shipped	Class 2, convertible to Class 3	Class 1, convertible to Class 2 and/or Class 3
Throttle	Included	Compatible, not included
Battery	733Wh	800Wh
Claimed range	Up to 75 miles	Up to 110 miles
Weight	68.5 lb	61 lb
Drivetrain	Shimano Altus 8-speed	Shimano Cues 10-speed with e-shifter and Autoshift
Front suspension	80 mm	100 mm

The REC is the heavier bike and the one with a throttle out of the box. Aventon lists it as compatible with a sensor switch between cadence and torque, and gives it regenerative braking that it says adds about 10 miles on descents. The ADV is 7.5 lb lighter with a larger battery, and ships as Class 1, which matters on paths that allow Class 1 only. Both have a 300 lb total weight limit.

If the review you read covers the Level 3

Aventon lists the Level 3 with 864W peak power, 4G/GPS anti-theft, 28 mph and up to 70 miles. A review of the Level 3 or Level 3 Step-Through describes that bike, and none of its figures carry over to the Level 4.

Abound SR or Abound LR

The two Abounds share more than they differ. Both use the same 750W hub motor (1,188W peak), a 733Wh battery, a step-through frame, 20-inch wheels, Class 2 and a claimed 60 miles. Both are rated for 440 lb in total and 143 lb on the rear rack.

The difference is length and seats. The SR has a 45-inch wheelbase and is listed for "a single passenger." The LR stretches to 52 inches and Aventon lists it for up to two, describing it carrying "two children." The LR weighs 88 lb against 80 lb for the SR, which is the price of the extra length when the bike has to be moved by hand.

Step-through beyond the Pace

Aventon's budget step-through collection includes the Aventure 3 Step-Through, Level 4 REC Step-Through, Pace 5 REC Step-Through and both Abounds. The Pace 5 REC is the one Aventon calls "our comfort-focused cruiser bike," with a 750W hub motor, 733Wh, 28 mph and a 330 lb limit on a rigid fork. The Aventure 3 also comes in a step-through version, which the collection lists with the same 4-inch fat tires, 1,440W peak and up to 65 miles as the step-over. The step-over weighs 76 lb, has an 80 mm fork and a 400 lb total limit.

The two lightest and the two built for trails

Soltera is Aventon's lightweight city family. Aventon lists the Soltera 3 ADV at 37 lb with a belt drive and the Soltera 2.5 at 46 lb with a Shimano 7-speed, both with a 540W peak motor.

Current and Ramblas move to mid-drive motors and trail suspension. The Current ADV is a full-suspension bike with 150 mm up front and 140 mm at the rear, the Ultro X motor at 110 Nm (120 Nm in Boost), 800Wh and 56 lb. The Ramblas ADV is a hardtail with a 130 mm coil fork, the a100 mid-drive at 100 Nm, 708Wh and 54 lb, and no throttle. Both ship as Class 1.
