Mechanical Parts Safety
- Fastening components:
1.1. The handlebar, head tube and saddle tube must be locked with 18Nm torque.
1.2. Locking force of 15-17 KGF is required on quick disassembly parts.
1.3. The front wheel nut locking torque needs to reach 18Nm, and the rear needs to reach 30Nm.
- Lubrication: The chain, flywheel and headsets need regular maintenance. Drop a little oil onto the chain, and apply drops every month.
- Adjust the rear ends of the chain. Loosen the nut, adjust the rear wheels front and rear position as needed to achieve the chains proper tightness, the middle position of the chain if pushed down with your finger should only drop 10-15mm.
- Pay attention to the front and rear brake blocks, if worn they should be promptly replaced, to avoid loss of braking and wearing the aluminium ring.
Rear Wheel Lock
Located at the back of the bike is the wheel disabler, this has been designed to prevent the wheel from moving when locked, which will foil people who attempt to steal the e-bike.
Assembling Your E-Bike
Adjusting The Front Braking System
The right brake lever activates your front brakes. Check the right hand braking handle as shown below, there should be full front brake pressure when the lever is pressed halfway. If the clearance spacing is different on the left and right pads, you can adjust the adjusting screws on each brake arm until the distance of the two clearances are the same. Loosen the spring tension adjusting screw, then tighten or loosen the brake cable to make the clearances between the brake pad and the wheel rim to be approximately 1.5-2mm. Tighten the tension screw when the clearances of the right-hand-side and left-hand-side pads are equal.
Adjusting The Rear Braking System
The left brake lever activates your rear brakes. Check the left brake lever the same way as checking the right brake lever but on the rear brake, adjusting the adjustment screw as needed. If this does not work, loosen the nut of the brake cable anchor bolt, then loosen or tighten the cable until the proper tension is reached. If this still does not work, you can adjust the clearance fine adjustment screw, and keep the clearance of the internal brake pad the same. Adjust these parts until the rear brake works correctly.
Adjusting The Front V-Brake Pad
Adjust one side first and then adjust the other. Please make sure the clearances between the brake pad and the wheel rim is approximately the same on both sides, the optimal clearance width is around 1.5mm. Tighten the nut after you have finished adjusting.
When emergency braking, your weight will shift forwards, reducing the load on your rear wheel. This can cause your rear wheel to slip, which is dangerous, especially when riding downhill. When emergency braking, keep your weight back and as far down as possible. Brake smoothly and remember your front brake will take more load when braking harder.
Installing The Front Wheel
Rest the front fork on the hub axle. Use the included washers and nuts to tighten the wheel to the bike. Please note the unique shape of the washers, the latch must be inserted into the hole on the fork, before tightening. When tightening the latch it should lie flat against the fork when in the closed locked position. If you replace the wheels, please tighten the nuts according to the recommended torque; the rear wheel torque should be no less than 30Nm while the front wheel torque should be no less than 18Nm.
Inflating The Tyres
- Remove the valve cap.
- Briefly press down on the valve to make sure the valve doesn’t stick and to remove any loose dirt.
- Press the pump nozzle onto the tyre valve stem as far as it will go.
- Lift the thumb lock lever into the locked position.
- Pull out the end of the bicycle pump and push down to start inflating the tyre, continue to do this until you have reached the desired tyre pressure. Do not inflate beyond the maximum tyre pressure – printed on the sidewall of the tyre.
- Release the thumb lock by pushing the lever back down.
- Remove pump nozzle from the valve stem.
- Replace the dust cap.
Installing the Handlebars
First insert the steering tube of the handlebars, then stand in front of the e-bike and keep the front wheel between your legs, hold the handle bar with both hands tightly, and then adjust the handle bar angle preferably so that the handles are at a right-angle with the handlebar tube, the height of the handlebars should be adjusted to your personal size and preference. Please do not extend the handlebar height over the maximum limit line. Once the angle and height are correct be sure to correctly tighten the nut at the top of the stem. Please do not extend the handlebar height over the maximum limit warning line or you may cause injury.
Installing the Seat/Saddle
Insert the seat post and adjust the seat height as follows:
- Sit on the bike saddle.
- Try to reach the pedal with your heel when it is in the bottom position. Your knee should be more or less fully straight.
- Place the balls of your feet on the centre of the pedal. If your knee is now slightly bent, the saddle height is correct.
- Never adjust the saddle so the minimum mark (marked on the seat post) is above the top of the seat tube, otherwise you could injure yourself or damage the seat post! Firmly tighten the seat post clamp with the quick release lock so that it lies flat against the frame.
- Check that the saddle cannot move once the quick-release is closed. If it does move, tighten the adjusting nut, until you need to use the palm of your hand to close the quick-release lever. CAUTION – Be careful not to trap your fingers when locking the quick release mechanism.
Adjusting The Chain
Release the rear hub nut and adjust the position of the hub to adjust the chain tension (the chain slack should be 10~15mm), align the chain wheel with the rear sprocket so that they are in the same straight line, and then tighten the rear hub nut. Rotate the crank set counter-clockwise, the chain should have the appropriate tension and run smoothly. CAUTION – Keep loose clothing away from the chain when riding as it may become tangled and cause injury.
Installing The Pedals
Normally the pedals are marked with an “L” for left or an “R” for right, if they are not marked then they can be used on either side. Please install accordingly, otherwise the crank arm can be damaged.
Installing The Front Mudguard
The headlamp comes pre-installed, however to attach the mudguard this must be loosened. Remove the nut on the back of the head tube, pass the mudguard over the tyre and hook the latch onto the bolt, then retighten the nut, both the headlamp and mudguard should now be in place. The mudguard spokes attach to the front fork, and are tightened into place by using the included washer and bolts onto the front wheel hub.
Your eBike comes fitted with an LED night light. The night light must always be turned on when riding in the dark. To turn the light on press the light button on the left handlebar. To turn off the light press the button again. Be sure to regularly check that the LEDs are working and replace as needed. Replacement LEDs are available from www.scootercity.co.uk.
Clean using a soft bristled brush to remove dirt and then washing with warm water. Do not apply water directly to rear drum brake, motor and hubs to avoid performance drop or shortening of life expectancy. Do not use steam, a hose pipe or high-pressure water gun to clean. Do not wash your eBike with the battery charger connected to the battery whilst charging to prevent the possibility of electric shocks. Do not submerge the battery in water or use to much water near the battery. After cleaning, dry your bike using a soft cloth.
As with all mechanical components, the bicycle is subjected to wear and high stresses. Different materials and components may react to wear and tear or stress fatigue in different ways. If the design life of a component has been exceeded, it may suddenly fail, possibly causing injuries to the rider. Any form of crack, scratches, or change of colouring in highly stressed areas indicate that the life of the component has been reached and it should be replaced.
For composite components, impact damage may be invisible to the user, the manufacturer shall explain the consequences of impact damage and that in the event of an impact, composite components should either be returned to the manufacturer for inspection or destroyed and replaced.
- After an accident or crash you must take your eBike to a bike repair specialist to make sure that it is safe to ride. Be aware that damage may not be visible. Failure to do this may result in serious injury.
- Any form of crack, scratches or change of colouring in highly stressed areas indicate that the life expectancy of the part has been reached and it should be replaced immediately.
- Ensure the battery is removed from the bike before carrying out any maintenance.
- Make sure that all screws and bolts are tightened securely and to the prescribed tightening torques before riding.
- You must always use genuine replacement parts when performing maintenance on your eBike.
- Regularly check the tyre pressures (minimum 50psi, maximum 75psi) and regularly check the tread depth of tyres.
- Regularly check the brakes for wear and adjust or replace them if needed.
- Check the wheels for buckles or damaged spokes and have them repaired immediately by a qualified bike repair specialist.
- Regularly check your light to ensure the LEDs are working and replace if needed.
- Check your wheels rims for wear. Each time the brake pads come into contact with the rim’s braking surface, a little rim material is abraded away. After a while, the rim will have a concave channel cut into it from the brake pads. When rims get this worn, i.e., this far past their intended life, there is very little structural material remaining to hold the rim together. This could be very dangerous as the wheel could crack while in use causing serious injury. Visually inspect your braking surfaces for excess wear. Usually this manifests itself as a concave profile on the rim. The easiest way to see this is by placing a straight edge (e.g. a metal ruler) across the rim surface. You'll see a significant area of daylight between the rim and the ruler if wear is excessive. Also look for grooving running around the rim, often caused by grit lodged in the brake blocks. These grooves can be the first places that the rim can fail. If the rims show signs of rim wear they must be replaced.
1.1 Before each ride, check whether tyre pressure is appropriate. Normally, the pressure is 125KPa for front wheel and 175KPa for the rear wheel.
1.2 Any cracking or abnormal wear on the tyres or rims.
1.3 Any nails, stones or glass stuck inside the tyres.
2. Brakes work normally?
3. Any damage on the charger and power cable?
4. Front and rear hub nut tightened? Throttle and turning mechanism parts loose or worn?
5. Brake pads worn?
6. For folding E-Bikes, check locking mechanism is secured.
7. Chain drive mechanism.
8. Crank arm worn out? Smooth rotation?
9. Wheel spokes loose or broken?
= Check = Adjust/Replace = Lubricating
