Urban Arrow utility
For transport of goods, tools or personal effects . Make your own box or rig and install them by using the four mounting holes provided. Goods can also be strapped down thanks to the shape of the frame that allows hooks to grip. The bike shares the same base as the ‘family’ version and can thus be converted later.

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 rear carrier rack accessory, are made of steel.
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:
|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 range1 - Eco mode2||not tested yet||not tested yet|
|Real life range - Turbo mode3||not tested yet||not tested yet|
What it means in real life is that you can expect that the CX offers more power assist when going up very steep hills. Travelling on normal level ground there will not be any difference. Both motors are capped at the same speed (27.5 km/h) and will mostly consume the same amount of power. Note the difference in battery capacity, though.
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.
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.
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.
The bike does not need to come back to the shop for a check-up after purchase (unless an unusual sound or similar develops). Its initial service should be carried out at 500 km, and thereafter every 1000 km. However, for an Urban Arrow that is used gently, mainly on the flat and kept indoor, the service interval can be extended up to 2500 km.
Things to look out for as an ownerThere are some little things that you should look out for as an owner.
- These two little bolts for the brake mount will work loose. It is not visible when this happens, so the only way to find out is by fortnightly tightening with a 5 mm allen key. It has to do with the thick aluminium material used in the frame. Threadlock (call it glue for bolts), won’t help. Failure to look after this may lead the brake disc to spectacularly selfdestruct and then cost you money.
- Wheel nuts, again fortnightly. Use a 5 mm allen key for the front and a 15 mm ring spanner for the rear.
- In total 4 bolts for the stand mount, again 5 mm allen. These need to be adjusted now and then. Too tight and the stand does not move freely as it should, not tight enough and the bolts may work themselves loose and parts get lost. The game is to find the sweetspot where the stand flings itself up at a speed that you are happy with!
- The 4 large frame bolts. You will see when they need tightening when a gap appears, see picture. If there’s no gap, then all is good. Use a 6 mm allen key.
