What I said about the Aventon Abound SR
If you want to carry a small child on the back for school runs and grocery trips, the Aventon Abound SR is a really nice option.
If you want to carry a small child on the back for school runs and grocery trips, the Aventon Abound SR is a really nice option. I tested it for several weeks and had my kids on the back. You get a stable kickstand, foot pegs, wheel guards, a plush rear seat pad, hydraulic disc brakes, turn signals and a 750W motor. SR stands for standard rear. It's shorter than the Abound LR, but you still get a big rear rack. If you don't need the passenger seat, it works as a cargo e-bike with bags on the back. My one real question mark was the battery. I couldn't tell how to take it out, so I assumed you'd charge it on the bike. Aventon's own pages now say it's removable. More on that below.

Liked
- Room for a small child on the back, or a shorter adult
- Very stable kickstand when a passenger climbs on
- Foot pegs that click up and down, plus mesh wheel guards and a long chain guard
- Plush rear seat pad and back pad
- Handle under the front seat for small passengers
- 750W motor
- Hydraulic disc brakes front and rear
- Turn signals and a brake light
- Sleek, smaller color display
- Front fork suspension and a suspension seat post
- Front and rear fenders standard
- Step-through frame that's easy for shorter riders
Didn't
- Plastic pedals
- Unusual charger plug, so you'll need Aventon's charger
- I couldn't figure out how to remove the battery
- The front rack costs extra
What I said about the Rad RadRunner 3 Plus
If you'll ride it to work five days a week, or you're replacing a car, the RadRunner 3 Plus is worth it. If you won't ride it that often, don't buy it new.
If you'll ride it to work five days a week, or you're replacing a car, the RadRunner 3 Plus is worth it. If you won't ride it that often, don't buy it new. I tested this utility e-bike for several weeks with the passenger package, the center console and the front rack. It carried my kids, hauled backpacks and handled mud and gravel well. What I'd change: the saddle is too flat, the battery is only "semi-integrated" and it uses a cadence sensor. At this price I'd like to see a torque sensor.
