Bike Assembly Options

1)  85% Assembly Option 

Available to Mainland UK addresses only, Estimated delivery time 2-5 working days.  We will dispatch orders received by midday that same day and our chosen courier will deliver direct to your door.  You will need to be in to sign for the delivery and bikes will be delivered boxed, 85% assembled.  Final assembly should be conducted by someone competent with the basic mechanics of a bicycle, if you require the help of your local bike shop please be aware the service will be chargeable

2) 99% Assembly Option 

Electric bikes are delivered 'built and ready to ride'. This means one of our trained, expert mechanics has fully assembled your bike in our workshop, applied protective packaging and re-boxed it for our courier to deliver it to you. After delivery you only need to make minor adjustments.

On arrival please complete the following:

  1. Remove the electric bike and any documentation/spare parts boxes from the outer carton and take off any protective packaging.
  2. With the bike on the ground or in a work stand, loosen the bolts on the handlebar stem where it meets the fork, line the handlebars up to the front wheel and re-tighten.
  3. In some cases you may also need to adjust the handlebar angle. To do this please loosen the bolts on the front of the handlebar stem where it meets the handlebars and rotate the bars until it is in a comfortable position, then re-tighten bolts.
  4. Your left pedal will already be fitted, so take the unfitted pedal and screw it clockwise into the threaded hole on your crank arm. We trial fit these prior to dispatch to ensure there is no cross-threading, so please take extra care when fitting.
  5. Adjust your saddle height if necessary by loosening the seat clamp and adjusting it to a suitable height. We recommend that your knee is slightly bent at the bottom of each pedal stroke whilst sat comfortably.
  6. Double check that every bolt you have adjusted is tight.
  7. We recommend charging your ebike to full capacity before you ride it to help the long-term health of your battery. To see if there is sufficient level of charge please check the handlebar display.

Please note - we complete the same pre-departure assembly on folding electric bikes, but dispatch them folded in their original box.

If you require the help of your local bike shop, please be aware that the service will be chargeable.
