Urban Arrow family

Urban Arrow family

Primarily for transport of children, but you will be surprised how many other things you will be carrying too. The electric assist makes you tackle hills and headwinds like a pro and allows the bike to keep with busy traffic. Add plenty of useful accessories, such as an extra bench, a tent or a rear carrying rack. The only thing you will regret with this purchase, is that you didn’t do it sooner.

Materials used

The aluminium frame is light, does not rust, and scratches in the thick paint do not appear as visible had it been steel. Aluminium is not as strong as steel, but the Dutch have chosen walls thick enough not to crack should the bike fall over. I have yet to see an Urban Arrow with frame failure.
The front wheel fork, the steering rod and the optional rear carrier rack, are made of steel.
The cargo box is made of a dense and elastic material called expanded polystyrene (EPP). It is very durable and dents, that may for instance when bike falls on its side, amazingly disappear by themselves. It is not the same material that is used in bicycle helmets, which intentionally is made to be brittle.


Electric assist

The Urban Arrow is powered by one of the industry’s finest systems, the Bosch mid-motor (or crank motor). It is easy to use, reliable and highly efficient. Three internal sensors that take 1000 measurements make the motor behave in a very precise manner. Typical power consumption for ordinary use is around 10 Wh/km, although if you are modestly sticking to Eco mode, it is as low as 3 Wh/km. The choice is between two different motor and battery systems:

Performance Performance CX
Torque max 50 Nm 75 Nm
Pedalling assistance max 260 % 300 %
Battery 400 Wh, 11.6 Ah, 36 V Li-ion 500 Wh, 13.0 Ah, 36 V Li-ion
Real life range1Eco mode2 70 km 85 km
Real life range – Turbo mode3 not tested yet not tested yet

What you can expect from the Performance CX is more power assist when going up very steep hills. Travelling on normal level ground there will not be noticeable difference. Both motors are capped at the same speed (27.5 km/h) and will consume the same amount of power. The battery bundled with the CX has more capacity, thus offering a better range.

1 Typical use as tested by Amsterdammers, with a bit of hills and some cargo etc.
2 Eco is the lowest of the four power settings; giving you less assist, but more range.
3 Turbo is the highest power setting; shortens the range, but more fun.


Brakes

Do not settle for anything else than hydraulic disc brakes when it comes to cargo bikes. The Urban Arrow uses the excellent Shimano Deore system with discs of 180 mm diameter front and back. The factory-fitted brake pads last 300–700 km, but once worn out, we replace them with an aftermarket type that lasts 500–1000 km.


The Gears

This bike has an unusual gear hub called Nuvinci N380. It is operated by a gripshift on the handlebar and instead of presenting different gears to choose from, it allows a smooth and continuous selection of any gear ratio within the range of the hub (380%). It is a heavy piece of equipment and offers less efficiency than a conventional gear hub, but on an electric bike it makes perfectly sense.


Service intervals

The bike does not need to return to shop for a check-up after purchase (unless an unusual sound or similar develops). Come back to see us after 300 km to have the brake pads looked at. We will then give an estimate as to when the initial service is due, usually 500 km. After the initial service, the bike should be fine for another 1000 km.
