Hi mooreb123, welcome to the forum. When you charge the battery, will it give you a full charge approx 4 hours? If you can go about a mile, it should indicate that the motor, controller and other bike sensors work fine. I would suggest: measure the output of the battery when you finish charging and measure it again after the cut out. Just to see if the battery is behaving abnormally. We have many experts here in the forum, so you should find some useful thoughts.

Hi Deano, We are a electric bike manufacturer, we don't manufacture battery. But we test their performance before we introduce them in our range. Lishen is well known for solid power cells and the class A cells performance fantastically on our bikes. Samsung is another maker of lithium batteries, it is not on our bike yet as we are testing them. Best regards

spelling error Hi Vectra, I made a spelling mistake replying your email you sent earlier on. The sport is 17.2 kg without the battery. 20Kg with the battery. Regards

Hi Flecc, yes..they are fantastic cells LiFeMgPo4. We have users using it for 2 years and still going strong. They are power cells, but low in capacity/weight. The parameter consistancy is brilliant. Since last year, we also explored low weight batteries, but we have a very strict rule for the battery manufacturer, only Lishen CLASS A cells as they are number 1 in China and most professional. We are testing out Sumsang CLASS A cells too at the moment.. did you come across them before?

Hi Flecc, the bionx system, do they use the water bottle mount? I have had a look at their mount....a little awkward for me. Battery mount like the bosch system, i agree, will not be suitable for step through.. I wish I would do a survey here...which one do you think people like the most? 1: Mounting in the front of seat tube (Bosch) 2: Panasonic mounting 3: Bionx mounting 4: Back carrier mounting regards Frankie

Yes another question to ask you flecc, What is your opinion on battery mounting ? which is the best place? back rack? water bottle mount or in frame...?

You seem to love SB motors...well they are good motors...you should come with me next time to see their production line... Alot smaller than I thought the first time I went...Dont know about now...

I see. I visited SB when I went back for chinese new year. I think they have good research team ...people who want to find out more about improving their motors.. But rumor says they have copied the design of MD ( Min da ) motor with the planetary gears. SB initially used metal gears, but due to noise, they now change to Nylon...which is much better even though it has question of its strength. Just rumour, within chinese e-bike industry...haha but SB are now very good motors as they start partnership with a Controller company to produce hall sensorless motors.. frankie

Hi Tangent, The motor is MD motor. I am not quite sure what you mean by SB... Frame size 460mm (18') Bike weight 23.5kg (including the battery) and battery weights 4.5kg The battery is locked in place like every other electric bike. HOwever, need quick release of the seat. We have tried some of the seat that can bend over. but some of them rattles, hence dropped the idea. Chain wheel 42 T rear cogs : 14-16-18-20-22-24-28 RRP 849 from only dealers. replacement battery 299.

Really wanted to challenged our bike. so did another road test yesterday out of a blue. If anyone knows the terrain I was on, you can run the same route with your electric bike. Harrogate to Wetherby Anyway , Here is the route in detail on google map Mode : Throttle only. Route: Harrogate to Wetherby and return 8.6 x 2 = 17.2 miles Google map link" Harrogate, North Yorkshire HG1 5DH, UK to Market Pl/A661 - Google Maps Time: set off from harrogate at 18:25 , reach Wetherby market place at 19:12, sent a picture to my collegue while having a cigi, and get back to harrogate at 19:50 pm Terrain : quite Hilly Average time for single trip : 38 mins Battery indication after the test: Low ( still going but less acceleration) Anyone can share their throttle only test route? http://www.3eelectric.com/img/cycle-1.jpg

Is it bionx system? Is that really bionx or developed by CUBE? Look really nice.

No, just for future reference, thinking of using the system for some of our models

Hi everyone, looking for crank system bikes, used, just to have a try out and learn a bit more. panasonic system prefered. Looking to buy one. best regards Frankie

Hi Alex Hi Alex, Yes they are from Wuxing, because none of the maker is big enough yet to have their own control unit made, which brighter ideas will become reality. But they are famous in making throttles anyway now:) Best regards Frankie Ps: alex, just wonder what bike you have got:)

Hi Flecc Hi Flecc, Thanks for the info! Personally big fan of the crank system, but a bit too complex for the consumers i think. but i definitely will learn alot from your site about the system.
