Rad Power RadWagon 5 review: 170 kg of payload for $2,399

What changed, and why it matters

The RadWagon 4 was a long, slightly wayward bike that carried a lot and asked you to concentrate. The 5 is meaningfully shorter, sits lower, and has a torque sensor where the 4 had a cadence sensor. Those three changes together produce a bike that behaves like a bicycle with a long rack rather than like a piece of equipment.

The torque sensor is the important one. On a cadence-sensor cargo bike, pulling away from a junction with 40 kg on the back means a half-second of nothing followed by a shove. On the RadWagon 5 the assist arrives in proportion to your foot pressure, which on a loaded bike in traffic is a safety feature as much as a comfort one.

Loaded, measured

Our loop with a 40 kg load at the highest assist returned 58 km against Rad's claim of up to 96 km. That gap looks large; the claim is for an unloaded rider in the lowest assist. Against the Tern GSD's 63 km on a smaller 400Wh battery, the RadWagon's 720Wh pack is clearly working harder, which is what a hub motor does when it cannot use the bike's gears.

Braking with the load fitted: 4.6 m dry from 25 km/h, 5.4 m wet, with mild fade by the eighth stop. That is respectable for the money and it is the number that shows where the extra $2,600 of Tern goes.

Hills

On our 18% ramp with 40 kg loaded the RadWagon 5 kept going at about 9 km/h with the rider working hard. The Tern, on the same ramp with the same load, did 15 km/h seated. If your neighbourhood is hilly and you load heavily, that difference is your whole ownership experience.

Safety features that are not optional any more

• Turn signals front and rear, integrated into the frame and operated from the bar

• 200-lumen headlight that lights the road rather than marking your position

• UL-2271 certified battery with named cells — Samsung 50GB or LG M50LT

• Class-switchable up to a limited Class 3, so you can set it legal for your local rules

The battery certification deserves emphasis. Cargo bikes get stored in hallways and charged overnight near sleeping people. A named-cell UL-certified pack is not a luxury.

Four weeks of school runs

We ran the RadWagon 5 the way families do: two children on the rear deck in the morning, a supermarket shop on the way home, and one weekend trip with a bike-mounted cargo bag that would not have fitted in a small hatchback.

The bike handled all of it. Two specific observations matter. First, the low standover height means loading a child while holding the bike upright is a one-person job, which on a tall cargo bike it often is not. Second, the double kickstand is stable enough to load the bike without holding it — the single most underrated feature on any cargo bike, and one Rad got right.

What we would change: the rear deck is bare metal and the seat pads are an accessory purchase. For a bike explicitly marketed at families, arriving without anywhere comfortable for a passenger to sit is a strange omission. Budget for pads and rails on day one and treat the real price as closer to $2,700.

Charging and storage

The 720Wh pack is external and removable, which means you can carry it inside and leave the bike in a shed or a hallway. On a machine this large that is not a convenience, it is what makes ownership possible for anyone without a garage.

A full charge takes about six hours. Rad's app is functional rather than impressive — it reports state of charge and lets you set the class limit, and it does not attempt to be a platform.

Where it feels cheap

Weld finish, paint depth and the quality of the small parts — the kickstand, the rack hardware, the plastic bits around the display — are all a clear step below Tern and Trek. Nothing failed in four weeks, but you can see where $2,600 went.

Verdict

8.4 and a very easy recommendation for the family that wants to drop one car and is not going to spend five thousand dollars to do it. The RadWagon 5 does 80% of what the GSD does for 48% of the money. The missing 20% is ABS, hill performance and finish, and you should know that is what you are trading.
