Actually cheaper than I thought !

Has anyone got any experience of adding a motor to a hand cranked trike ? Got a friend who is thinking about it, so is looking for sources of info/advice ? Any help appreciated. Paul.

Just had a phone call from a mate who uses Cost co a lot and wanted advice on an electric bike they had for sale. It is called a Jetson. He believed they were being sold for about £875. I cannot find it on their web site so it maybe a in store only deal. However I did find a you tube clip of one in an American store. Has anyone come across these before or got any views on the quality etc.

Thanks Peter, will be in touch. Paul

I began this thread in the introductions section but things have moved on.... The motor is not assisting, I had just returned to my bike, replaced the display : The Bosch display looks normal except there is no speed display. The battery is fully charged (shows all leds when on the charger). On the bike the battery shows one battery led. The display shows only 3 bars (this is probably the status when everything last worked) If I press and hold the battery button whilst on the bike, when I release it all leds light up,but over say twenty minutes dwindle to one led. Returning it to the charger all LEDs show up. The thumb switch will change the power assist and information on the screen. The lights do not switch on from the display screen. I have charged the display unit using the USB port overnight. I have cleaned all the contacts with electrical contact cleaner and put a little vaseline on. Took the bike to 50cycles. Tried different display and battery. Still no assist. Left with 50 cycles. 50 cycles shared error codes with Bosch who report that it requires new motor. Estimate is £600 plus. Can anyone offer any advice - is there someone out there repairing these motors ? Paul.

Have taken it into 50 cycles. Awaiting a diagnosis.

Update : I have observed that when the battery is off the bike and I press the button all leds light up when I mount the battery on the bike they gradually (over 10 or 20 mins) step down to just one led. T%he display screen can be on or off the bike the same thing happens.

Thankyou for the quick response. Do I have to remove the crank ? There looks to be two covers, upper and lower, do both need to come of ? Is there a gasket or seal there I need to be aware of ? Paul

I have just joined. I have had a Kalkhof Endeavour BS10 Since Oct 2014. I have had so much fun on it, using it for a 12 mile commute 2 or 3 days a week arriving at work with a smile on my face ! But my favourite is going out sunday morning and catching up with the lycra brigade, gliding past them up hill. Only had 3 problems : The handlebar switch for power level and to change the information screen went faulty, 50 cycles posted out a replacement straightaway. The chain jumped off and jammed between the motor housing and chain ring.Very difficult to free. However only happened once. Bust the rear rim, suspect too much load in the panniers and me and bumping down a kerb. I am very interested in following the speed pedelec legal debate and how to register. However I joined the forum because the bike has just gone wrong and left me stranded with a 10 mile non powered pedal home ! (Good for calorie burning !) The bike is not giving any assistance. Here are some details : The Bosch display looks normal except there is no speed display. The battery is fully charged (shows all leds when on the charger). On the bike it shows one battery led. The display shows only 3 bars (this is probably the status when everything last worked) If I press and hold the battery button whilst on the bike, when I release it all leds light up. The handle bar switch will change the power assist and information on the screen. The lights do not switch on from the display screen. I have charged the display unit using the USB port overnight. I have cleaned all the contacts with electrical contact cleaner and put a little vaseline on. Has anyone any suggestions on next steps ? Would this be better on a different thread ? Paul.
