What I said about the Freesky Ranger Air M-540
A dual-motor step-through fat-tire bike that climbs steep hills; heavy at 95 lb.
Buy the Ranger Air M-540 if you want a dual-motor step-through for steep hills. The front motor pulled me up steep inclines, and I said it has plenty of power. It also has a fork plus a rear shock, hydraulic brakes and a throttle that works from a stop. I tested it for several weeks. Skip it if you need to lift your bike. Freesky lists it at 95 lb. Also skip it if you want dual motor all the time without pressing a button. It starts in rear-wheel drive every time.

What I said about the REVR CM7
A comfortable full-suspension step-through for gravel commutes; heavy.
Buy the REVR CM7 if your commute mixes pavement with dirt or gravel and you want a soft ride. It has a front fork and a rear shock (2:18 to 2:47), Zoom hydraulic disc brakes on both wheels (0:56 to 1:10, 2:08 to 2:12), and knobby fat tires that held traction on dirt slopes in my testing (3:50 to 4:09). I said it suits a medium to long commute with some gravel on the way (4:47 to 5:03). Skip it if you want a light bike or a torque sensor. It's a heavier e-bike because of the fat tires and rims (4:28 to 4:37), and it uses a cadence sensor with a crankset that didn't feel as smooth as some others (2:55 to 3:07). REVR lists 70.84 lb. The deciding factor: comfort and brakes versus weight. If you carry it up stairs, look elsewhere. See the CM7 at REVR (REVR's current CM7s showed $1,399 in search results on Oct 23, 2026; confirm at checkout)
