Step 1 of 7

Before you start

Unpack everything and check it off before you start. Missing something? Call us before you assemble.

Bike, battery, charger, headlight, pedals (left and right) and two keys
Ampd Bros tool kit and starter bag, owner’s manual and sticker
Mudguards on select models
GO App models (ACE Series 5 and Taipan): your QR code is on the bike near the battery, with a copy in the starter bag. Keep it safe.

Set yourself up. Clear a flat, well-lit space you can walk around. Keep the box and packaging until you’ve ridden a few times, and take photos of the bike as it arrived. They help us help you faster.

Front wheel

Fit the front wheel first so the bike can stand on its own. Check the end of your axle to see which type you have.

Through axle: lever on the axle end

Loosen the four pinch bolts at the bottom of the fork legs, two on each side.
Stand the wheel between the fork legs with the brake disc on the caliper side, then lower the fork, guiding the disc gently between the pads.
Adjustable fork models: slot the axle nut into the hex recess on the disc side, narrow end first, so it sits flush.
Slide the axle in from the side opposite the disc, threaded end first, and turn it clockwise by the lever until snug.
Close the lever flat against the fork. It should need firm hand pressure. If it closes easily, open it, give it another turn and close it again.
Re-tighten all four pinch bolts until firm, then spin the wheel. It should run straight with no disc rub.

Do these steps in order. Tightening the pinch bolts before the axle is closed forces it out of alignment, which damages the bearings and can misalign the brake disc.

Fixed axle: nuts on each end

Remove the axle nuts and washers and keep them together.
Stand the wheel between the fork legs with the brake disc on the caliper side, and guide the disc into the gap between the pads.
Lower the fork so the axle seats fully into both dropouts.
Refit the washers and nuts, washers against the fork.
Centre the wheel and tighten both nuts evenly, a little at a time on each side, until firm.

Check it every ride. A front wheel that isn’t secured properly can come loose while riding. The disc must sit centred between the pads.

Handlebars

Work slowly. Twisted cables can knock parts out of adjustment or disconnect plugs.

Stem clamp: all models except the ACE Mini

Loosen the four upper bolts that clamp the handlebars, and centre the bars in the clamp.
Tilt the bars to the angle you want, with the front wheel straight and lined up with the bars.
Tighten the upper bolts diagonally: top-left, top-right, bottom-left, bottom-right. Repeat until firm so the clamp closes evenly.
8-bolt stems: the four lower bolts fix the stem to the fork. Check all eight are tight.

Handlebar posts: ACE Mini

Loosen the two bolts on each side of the fork where the posts insert.
Insert the posts up to the marked safety lines. Never ride with the posts above these lines.
Tighten the two bolts on each side until firm.

Brake levers and the display should be secure but not overtightened, as plastic housings can crack. Take care adjusting brake levers: it can upset the motor cut-off sensor.

Pedals

Pedals are side-specific, and the left one is reverse-threaded. Getting this wrong can strip the thread.

Find the L and R markings on the pedal spindles. R goes on the chain side.
Start each thread by hand. It should turn smoothly. If it binds, stop and check you have the right pedal.
Right pedal tightens clockwise. Left pedal tightens anticlockwise.
Finish with a spanner until firm.

Easy way to remember. Both pedals tighten when you turn the top of the spanner towards the front of the bike.

Headlight

Fit the headlight to its bracket and connect it.

Mount the headlight on the bracket and tighten it, angled slightly down towards the road.
Connect the cable at the lower plug near the front fender, not the wire by the brake levers.
Once the battery is in, hold + on the display for 5 seconds to check it switches on.

Battery and first charge

Fully charge the battery before your first ride.

Plug the charger into the battery’s charging port first, then into the wall, and switch it on.
The charger light shows red while charging. After several hours it turns green: the battery is full.
Unplug from the wall, then the battery. Lock the battery into the bike with the key and check it’s secure.
Turn the master switch on the battery ON, then hold the power button on the display.

Safe charging. Never charge overnight or unattended. Charge on a hard, dry surface, never on a bed, couch or paper, and only use the genuine charger supplied.

Final checks

Two minutes now, and before every ride.

25–28psi tyre pressure

Tyres at pressure and seated evenly on the rim. Never exceed the maximum on the sidewall.
Front axle lever closed firmly, or axle nuts tight.
Both brake levers feel firm. Disc rotor and caliper bolts tight.
Handlebars, stem, cranks, pedals and kickstand bolts tight.
Battery locked in, headlight and rear lights working.
Helmet on. First ride at PAS 1 somewhere open and quiet.

Quick tricks

The four things new riders ask us about most.

Headlight on or off

Hold + for 5 seconds. Works on every model. The small daytime running light stays on while the bike is on, for your safety.

Charge in the right order

Plug the charger into the battery first, then the wall. The charger checks the battery first, so the other way round it won’t start.

Hill Boost

A short burst of extra torque for steep climbs and hill starts. Hold M on Micro displays, or minus on Ultra displays (Pro, Demon, Taipan).

Clear your trip

Hold plus and minus together to reset the trip computer.

Something not right?

Missing parts, damage or a fault after assembly: lodge a service request and a technician will typically reply the same business day.

Important. Incorrect assembly can void your warranty and cause serious injury. Check your work against the manual and do a full pre-ride check before every ride. More help in the support centre.
