Tips and Important Information


Always Ride with Clamping Ring in closed position

The closed position is shown here:

Never Ride if the Bottle or Clamping Ring feel Loose

Clamping Ring should not close easily - resistance should be felt when turning the ring to the closed position. If this is not the case then the metal cage could be bent - this must be rectified before using the bottle on the bike.

Avoid Leaving your Bottle in Direct Sunlight

If you are outside and not cycling it is best to place your bottle in the shade on a warm or hot day. Like a smart phone or tablet, the bottle will heat up if left in direct sunlight on a hot day and if it gets too hot the protection circuits will prevent C1 from working until it is has cooled down.


Never store your battery for extended periods empty (flashing red indication)

Storing your battery for more than two weeks when the charge level is indicating flashing red can result in over discharge which will permanently reduce its capacity. Over discharge is not covered by the Warranty. To see charge level - invert your battery for about one second then return to vertical.


Storing your battery

If you do not intend using your bike for a while, such as storage over winter, then leaving the bottle with a 40% charge will keep it in the best condition. 40% charge means the bottle will be indicating purple charge level. Store your battery at room temperature in a dry place with the dust cap on and out of access to children. Never store your battery on a moving / vibrating surface (such as a washing machine). The bottle contains intelligent electronics such as an accelerometer which is designed to wake the Bottle with movement - if the Bottle is kept awake then the battery will drain at a much faster rate. See other battery warnings below.

Low Battery Mode

When your battery gets very low, Cytronex will automatically ramp down assistance to extract the last available power from the battery. Eventually when all assistance power has been used, assistance will be switched off and the Boost Button will flash red 5 times. If you press the Boost Button for assistance at this point, it will flash red again to show no assistance is available. However, bicycle lights will stay on and can be turned on and off, lights will work until the reserve has also been depleted, when the bottle will be turned off completely. The lights should last at least one hour after assistance has expired but we advise against using an empty battery for long trips if lights are needed.


Boost Button Illumination Appears dim

If your Boost Button appears to be dimmer than usual when switched on this may be because the power for bicycle lights is turned on, which changes Boost Button illumination to night mode (the brightness of the Boost Button day and night is settable with the Cytronex app). The power for bicycle lights is turned on or off by holding down the Boost Button for 2 seconds - you will see the colour change once, then change back again - release the button at this point to turn lights on or off.


Resetting Charge Level Indication

Periodically we recommend using a fully charged battery without recharging until assistance has expired and the Boost Button flashes red. This is not required for battery care – but it will ensure that your battery charge indication remains accurate.

Hub Gear Bikes

If you have installed Cytronex on a bicycle with hub gears it is important to use the Cytronex App to select "HUB GEAR" - if this is not selected the assistance is likely to turn off and on unpredictably at a variety of speeds.

Avoid leaving Bottle connected to PC for long periods

Leaving the Bottle connected via USB does not charge the battery - in fact it will consume a small amount of energy because the system will stay awake. So its best not to leave your bottle connected for a long time, especially if the battery is low.

Transporting your Bottle by Air

Requirements for transporting lithium batteries are strict and can vary by airline. If you need to transport your battery by air Cytronex is unique in having a method of separating the battery into two packs of 90Wh capacity each which can allow transport as carry-on baggage by arrangement with the airline, but you should confirm this with the airline before booking. We recommend using the Cytronex Bottle Packing Box for this and following the instructions to separate your battery (special tool required which can be purchased from us “HERE”. If you are sending your bottle by air transport courier then you must divide the battery into the two packs and use the Cytronex Bottle Packing Box - for air transport the battery charge level must indicate solid red.

Removing the Rear Wheel

Before removing the front wheel it is important to swing the spring loaded sensor head out of the way first - support the sensor bracket with one hand so it cannot move whilst pushing the end of the sensor downwards as shown in the photo. Once the rear wheel is replaced and secured flip the sensor back to its original position. Failure to flip the spring-loaded head out of the way is likely to mean the sensor needs readjustment.

Pressure-washing and transporting your bike outside a vehicle

Never pressure wash your bike as this could breach waterproof seals and force water into components, causing failure. When transporting your bike outside a vehicle - always remove the bottle, and we recommend placing a cover over the bike. If using a hose never point directly at motor axle and always avoid submersing motor axle and controller.


Do not attempt to open the motor casing

The motor is sealed and there are no user serviceable parts inside. Loosening or undoing the screws in the casing or the axle nuts nearest the motor will compromise the water resistance and void the Warranty.


Off-Road Riding

Cytronex C1 has not been fully tested in rough off road conditions so we do not recommend using your Cytronex Powered bicycle with assistance turned on when riding on rough un-surfaced tracks. Any damage caused by use on rough terrain is not covered by the Warranty.


Riding Unassisted

If you want to use your bike unassisted without the bottle then we suggest twisting the connector to the shut position so it does not move around.


ALWAYS cover the battery if it is raining when you remove it.

Place the protective cap over the connector when transporting the battery of when there is a possibility that the contacts in the battery connector could come into contact with metallic objects.


Bicycle Maintenance

Please refer to your bicycle owner’s manual to ensure you complete the bicycle maintenance required for your particular make and model.
