01 EBIKE BOOST BUTTON

Fitting the Cytronex C1 electric bicycle conversion kit to a bicycle does not change the way the bike rides when the system is off, so when the terrain is easy, you don’t need assistance. When the going gets tough, just press the ebike Boost Button and smooth, refined and virtually silent assistance powers you up steep hills and through head winds. A Cytronex C1 assisted electric bike rides like no other electric bicycle.

Ebike Boost Button turns on and off with a single press. If you press and hold for one second the button will change colour and provide a different power level. You can set the power for each colour in the C1 App. Whatever power level you choose – your Cytronex ebike will add that precise power level to your cycling effort. Press and hold the ebike Boost Button for two seconds and you can turn on the optional high power LED bicycle lights. Read more

02C1 App

Customise your ride.

The Cytronex water bottle battery connects to your PC via USB whilst in the Charge Shoe so you can use the C1 App. This allows you to set exact power levels and the brightness of LEDs – day or night. The App includes a diagnostic function – in the event of an issue you can send a log file to Cytronex and you can update your system automatically when new software is available. The advanced all British electronics can maintain a precise power level so you can enjoy riding with family or friends. No other ebike does this.

05 CYTRONEX SENSOR

One Sensor, Low Maintenance, Easy fitting

Our multi patented Cytronex sensor replaces the 3 sensors required by other electric bike conversion kits to comply with regulations and fits quickly and easily without bicycle tools. Cytronex sensor detects the movement of a rear sprocket to monitor pedalling and bicycle speed on most bikes and the ultra fast response means a brake sensor is not required.

Sensor head swings out of the way if knocked during bicycle maintenance and can simply be flipped straight back to the original position.

06MOTOR

Discreet small and lightweight motor packs enough power to easily climb hills
and silently pass even the strongest riders.

Our new hub motor wheel is available in disc or V-brake versions, black or silver to match your rear wheel and a variety of sizes to fit your bike. Selecting European C1 provides 25Kmh maximum speed and the USA version has a maximum speed of 20mph. With Boost off, the motor hub is not engaged and the wheel spins freely without resistance. The motor weighs just 2Kg and the complete C1 conversion kit adds just 3.6Kg,- start with a good bicycle and the result is often 5Kg+ lighter than a purpose built electric bike.

07 CHARGER

Compact Fast Chargers with Charge Progress Indicator

To charge – turn your bottle upside down and place in the charge shoe. The bottle LED will shine on the Cytronex logo to indicate charge level as charging progresses – if you are in a hurry you can see when you have enough charge for your journey.

Our compact fast chargers and charge indication function are perfect for topping up your battery when you stop for lunch or coffee – the Standard Charger will re-charge about 80% of battery capacity in 2 hours and the Fast Charger will do this in about 1 hour from empty.

Customer Reviews

Struggling with a new knee and a 26 mile each way commuter journey to Canary Wharf, I bought the Cytronex kit for my wonderful Thorn Raven Tour bicycle in 2018 and love it now as much as I did on my first commute. Having cycled to work for 33 years, my misplaced dignity prevented me from buying a traditional electric bike and Cytronex was the solution - a battery cleverly disguised as a water bottle! A single charge managed the 26 mile mostly flat journey and I bought an additional charger to recharge at work. Undoubtedly, without Cytronex, I would have resorted to public transport. It does not provide the exercise of an unassisted bike, but it nevertheless provides exercise and, critically, it has allowed me to continue the joy of cycling. The Cytronex powered lights are brilliant and very necessary to avoid the deer cycling home through Richmond and Bushy Parks on dark winter nights. I look forward to many further years of Cytronex assisted cycling. Winchester shop service is excellent - where else would someone reply to you at 2220 confirming that your bike was booked in?

I have been a serious cyclist for over 30 years, riding 2,000-3,000 miles per year. Now that I am 75 years old, I don't have enough leg strength to keep up with my fellow riders. Since I converted my bike to the Cytronex motor and battery, I am able to ride where and when I want. Consequently I just ordered a conversion kit for my second bike. Ya gotta love CYTRONEX!!!!!

About two years into ownership of my Cytronex C1 equipped Cannondale Quick Disk 3 and can't recommend the C1 tech - or the folks at Cytronex' Bridge Street (Chesil Roundabout) bike shop in Winchester - more highly. The C1 System got me back onto two wheels after serious illness, flattening out Hampshire hills whenever called upon, and never letting me down to date. No hill (so far!) unconquered. Perfect for circuits to Alresford, Stockbridge, King's Somborne, Owslebury etc. Completed 2019, 51 mile Wantage to Winchester last week in (imho!) v.respectable time of 3hrs 45 mins (av speed nearly 14mph) with c 25% of the battery left at the end, despite my looming 6'5" frame and manly 106kg mass (without XXL bike!). Shop staff always friendly and receptive too (fixing a broken spoke at short notice to allow me to ride last week). Great stuff - go for a test drive and see if it works for you - highly recommended!
