What I said about the Romatlink Dolphin
A passenger-ready folding fat-tire bike with a 1,440Wh battery and full suspension; heavy at 93 lb with mechanical brakes.
Buy the Dolphin if you want a full-suspension, passenger-ready e-bike that folds, and you care more about range than weight. I rode it for several weeks. It became our daily driver for taking the kids to school. The 48V 30Ah Samsung battery is the reason to buy it. We rode 25 miles and the display still showed 100%. Skip it if you have to lift your bike often, or if you want hydraulic brakes or a torque sensor. It weighs 93 lb. That's one of the heaviest bikes I've tested. It has mechanical disc brakes that take a hard squeeze at speed. The pedal assist uses a cadence sensor, not a torque sensor.

What I said about the Romatlink Rhino
A big, budget fat-tire bike with a 960Wh battery that fits tall riders; heavy, and out of stock when checked.
Buy the Rhino if you want a big, rugged fat-tire bike for commuting and light trails, and you're taller. I tested it for several weeks. I'm about 6'1" and was super comfortable on it. It has a 750W motor that peaks at 1,200W and a 48V 20Ah Samsung battery. At the sale price I saw, I said I'd definitely buy it. Skip it if you need to lift your bike into a car or up stairs. It weighs 82 lb. Also skip it if you want to raise the handlebars without buying extra parts.
