Okay full range to battery exhaustion is 50 miles which is great! For the first 10 miles it is very quick, decreases a bit to a steady level of power for miles 10-30, noticeably less power for miles 30-40 but still usable. Between 40 and 50 miles the assistance drops off quickly to an hardly...

Following about 3 and a half years riding my Cytronex Cannondale CX-3 (http://www.pedelecs.co.uk/forum/threads/cytronex-quick-cx-3.10112/) the battery finally gave up. I bought a new regular bike to improve on the frame fit, found Trek hybrids to suit my build better. Tried regular cycling for...

After 5000 miles the battery pack finally became decidedly dead in early 2015. Due to the poor fit of the original bike I bought a new bike and tried regular cycling for a year but really missed the assistance. I have since bought a new Lithium battery (not from Cytronex - got fed up of waiting)...

In the end I went for one of these Samsung 10.4 Ah batteries to replace my old Cytronex NiMh battery: http://www.brightonebikes.co.uk/store/p2/Samsung%C2%AE_cell_36V_10.4AH_E-bike_battery.html The battery weighs in at 2.5 kg, so only 0.5 kg heavier than old Cytronex NiMh battery, only marginally...

I would be curious if packs like this or this would work... Meant for balance scooters but seem ideal on paper.

Hi Trex, thank you for your reply and the useful suggestions for UK based battery suppliers. Seems as technology has matured, batteries have gotten larger in capacity but same size/weight, rather than offering same capacity with less weight. But I'm really after a small pack...I will enquire in...

Hi folks Considering harvesting my old Cytronex (with dead NiMh battery) to convert my new Trek bike as I'm missing the assistance. So I have the motor, 36V controller, but need new battery, BMS and charger. The main question is the battery issue. Initially I thought about a DIY RC LiPo...

I am selling my 36V Cytronex NiMH smart charger. Please see my eBay listing for details, pictures. http://www.ebay.co.uk/itm/301633025706 Offers considered!

After several winters of freezing cables, adjusting derailleurs and occasionally emergency stopping in traffic and ending up in the wrong gear, I have been trying bikes with different hub gears debating if my next bike should go this way. From trying bikes and reading around, I came to the...

Otherway around...it was the Samedi 28 Nuvinci, and sorry when I said riding position was too low I meant handlebars were too low down, and a more upright riding position would have been preferred. That's just personal preference though. Regarding gears, I really think the requirement for...

I have ridden a Cytronex bike for over a year, but have started to look at other systems again, mainly just to see what is out there now. I have just tried a Kalkhoff Agattu Impulse C8 HS (2013 software) at Oxford transport shop and 2 months ago rode the Bosch on a Moustache with NuVinci hub...

3500 miles - update. Motor drag has been reduced a bit following adjustment of disc brakes :rolleyes:. Motor initially made concerning clicky noises after the repair job, but seems to have 'run in' now. So would say everything is running well, except that pedal bearings are shot so the...

Hi Tony. Low speed control is quite good I agree. My suggestion for improvement was more on how it handles the maximum speed. I really like the way the motor 'takes up the slack' if you feel tired, to hold you at cruising speed without having to use a throttle, very simple and intuitive and...

Having had fun riding around on my Cytronex in the snow, I feel that the bike would benefit from some ability to modulate the top speed. For those who do not know, the (new) system engages power when you pedal, and stops when you stop pedalling or touch the brake (or turn it off). The motor...

Thanks for the info Jerry. In any case, your experience gives me confidence that I could have the motor replaced with another Tongxin at some point, it probably wouldn't happen again. Unless it is due to using it in rain, sub zero conditions and storing it in an unheated shed. I do like the...

;-) Yes and thanks all for the ideas on the motor alternatives. Having said that, it seems this just afflicts my motor and not generally the case for these tongxins. As for ownership timescales, my post was not a typo, but perhaps badly explained. Bought Oct 2011. April 2012, freewheel...
