Blix Sol X Comfort vs Aventon Level 4 REC

Two commuter e-bikes at a similar price, compared on the same normalized specs. Both scored by us, both reviewed in full.

The verdict

Both score the same on Genius and cost almost the same, so this comes down to whether you value the Blix's higher payload capacity and lighter frame or the Aventon's stronger torque and bigger battery for range.

Buy the Blix Sol X Comfort

Buy the Blix Sol X Comfort if you want to spend $100 less, need the higher 400 lb payload capacity, or want a bike that's 7 lb lighter to carry up steps or load on a rack.

Buy the Aventon Level 4 REC

Buy the Aventon Level 4 REC if you actually climb hills or haul weight from a stop, since its 10 Nm torque edge and 119 Wh larger battery translate to more range and pulling power, and you're fine paying $100 more and hauling 6.5 lb extra.

The differences that matter

  • Blix Sol X Comfort costs $100 less.
  • Aventon Level 4 REC pulls harder from a stop and on hills, by 10 Nm of torque.
  • Aventon Level 4 REC carries 119 Wh more battery, which is the main thing that sets how far you get.
  • Blix Sol X Comfort is 7 lb lighter, which you notice lifting it or carrying it up steps.

Who each one is for

Blix Sol X Comfort

Everyday commuters who want a comfortable, low-maintenance bike that can cruise on the throttle and carry a real load.

Aventon Level 4 REC

The everyday commuter who wants a long-range, low-maintenance bike and likes having a throttle for the days they'd rather not pedal.

The short version on each

Blix Sol X Comfort

What's good

  • The auto-shifting 8-speed drivetrain changes gears for you, so there's no guessing about which gear you want at a light or partway up a hill.
  • 70 Nm of torque from the 750W motor gets a loaded bike moving from a stop and up the everyday hills of a normal commute.
  • A throttle plus a switchable Class 2/3 setting lets you ride without pedaling and decide how fast, and where it's legal.

What to know

  • Value is the soft spot here. A few commuters with a similar motor and range come in for less money.
  • The electric auto-shifting is convenient, but it's more electronics to depend on than a plain cable-and-lever drivetrain.

Aventon Level 4 REC

What's good

  • A removable 733Wh battery with an up-to-75-mile claimed range, so you can pull it out to charge indoors and go days between top-ups.
  • A throttle lets you ride without pedaling, and you can switch it from Class 2 to Class 3 for a 28 mph top speed when local rules allow.
  • 750W and 80 Nm of torque pull the bike away from a dead stop and up city hills without drama.

What to know

  • No suspension and moderate 2.2-inch tires mean rough pavement and potholes come through to your hands.
  • The Shimano Altus 8-speed is an entry-level drivetrain, a notch below what some rivals hang on a $1,999 bike.
