Boost Electric Bike wireless display

    Your display Boost Electric Bike wireless display makes it easier to select your power mode and see your speed. Your display is wirelessly upgradeable so new functions are on the way – please join the Boost Electric Bike mailing list for updates.

    The Boost system is designed to be autonomous, and decide how much assistance to provide automatically. It is not like other systems where you have to set a constant power level and it will simply deliver that at all times. 

    Boost is continually adapting to your speed and cycling style and will even detect hills and automatically provide extra assistance.

    We refer to the Boost Wireless Display as the ‘display’; the ‘controller’ is the brains of the Boost system and controls the motor, and it lives in the base of the battery mount. The Boost Wireless Display is not the ‘controller’.

    There are two normal power profiles. 

    Eco mode

    In Eco mode, the display will show a ‘Down’ arrow.

    Eco mode makes it easier to cycle but it doesn’t accelerate the bike. It’s a gentle assistance while still relying on your leg power.

    Eco has three speed ranges; 3-8mph, 8-12mph and 12-15.5mph. As you pedal harder and reach the next speed band, you’ll release a higher level of boost.

    Eco is also designed to preserve battery life and the biggest use of battery is climbing hills. For this reason Eco mode does not attempt to provide extra assistance on hills.

    Boost mode

    In Boost mode, the display will show an ‘Up’ arrow.

    Boost mode aims to accelerate you and provide a noticeable push to your riding.

    On the flat, Boost mode will generally accelerate you and you’ll quickly reach 15.5mph, at which point the system enters a proportional assistance mode where it’ll intelligently adapt the power output to hold you around 15.5mph. If you pedal above this speed the motor will move into a power saving standby mode and until your speed reduces back into the legal assist range.

    Boost mode intelligently detects hills and will increase the power output up to the maximum safe level to make hills easier. The maximum level is as used in the ‘Super Boost’ mode, so if you’re on a hill in Boost mode, it’ll automatically adjust up to Super Boost as necessary.

    You should change into the same low gear you’d normally use to climb a hill; the Boost system is not designed to waft you up hills in a high gear. Please read ‘Boost and hills’ below.

    Super Boost mode

    Super Boost provides as much power as the motor can safely handle at a given speed. Press to get quickly accelerate up to 15.5mph. Super Boost mode is active for ten seconds and returns to the previous mode afterwards.

     

    Values on the screen

    Top number – Voltage

    Rather than trying to estimate remaining battery level, we have decided to show you the battery voltage level. Battery voltage level is a little like the water level in a water level; as you drink water from a water bottle, your water bottle level falls. In a similar way, as you use your Boost system, the battery voltage falls.

    Despite being a 36 volt system, the normal fully charged voltage level is 42 volts. As you use the battery its voltage falls. At about 30 volts the battery is empty and safety systems will kick in to stop damage to the battery.

    As the battery level decreases, its ability to maintain voltage when under load decreases. At 34 volts the battery is fairly low on charge, so if you get to a hill the power being drawn out of it could easily drag its voltage to under 30 volts. At this point the safety systems will kick in and you won’t have assistance.

    It is not possible to say with certainty how much battery level is left simply by looking at the battery voltage. There are various confounding factors which also make it harder to guess how much range is remaining.

    For example, if the battery is charged for a short time its voltage can quickly increase and look full, but this is not ‘real’ voltage; it’s an effect called ‘surface charge’. The best way to charge your battery is with an original Boost charger, and wait until the green light shows on the charger.

    Temperature has a big effect on battery performance. Cold batteries are much less able to maintain their battery voltage under load so may appear to be more empty than they actually are.

    We have found some customers try to drain their batteries almost to flat before charging, having heard about ‘memory effect’. This is a very old effect related to Nickel Cadmium (NiCad) batteries.

    This is the wrong way to use modern Lithium batteries and will damage them. You will get many many more charge cycles by charging your battery lightly and frequently back to full charge. Once the charger has shown fully charged, unplug the battery rather than leaving on charge.

    Boost and hills

    As discussed elsewhere, Boost is a rear wheel hub drive system and features a motor with class leading torque. Hub motor systems are best for smooth commuting and moderate hills, we say up to 8%. That’s not to say that the Boost system won’t make steeper hills easier, but you’ll have to be in an appropriately low gear and be doing a good amount of work yourself. If your speed falls below 4mph the Boost system will no longer provide assistance.

    If you are recovering from injury or beginning your fitness journey, and wish to climb hills in excess of 8%, the Boost system may not be for you. A mid motor/crank drive branded manufacturer e-bike may be better for you and these will cost in excess of £2,500.

    Please talk to your Boost dealer about your requirements as we want you to be delighted with your Boost-ed bike.
