I'm wondering why you're choosing the TSDZ2 over a BBSxx? I'm a TSDZ2 fan but I don't do mountain biking - just local rides along country lanes. mountain biking is a much harsher environment - jumps, standing on the pedals, powering up hills and so forth. I'm not saying the TSDZ2 is not up to...

It was greenbikekit.com - I order on 29th Jan - I wasn't given a shipping/delivery forecast but I'm anticipating a couple of weeks.

I'm thinking the Chinese New Year holidays may be the cause for no reply as yet. I'm awaiting a replacement BMS for my bottle battery as not only is the BMS not alowing a full charge but the discharge mode fails to operate sometimes too. I have twice now got the battery to fully charge by...

Thanks for the pics up post @tomtag regarding the thick wires running between the BMS and bottom connection area. And I'm assuming that once the hot glue sealant has been removed, the whole battery pack is pushed through the metal bottle case, top downwards? (Please confirm as this will be...

Interesting reading and for cyclists, safety on the roads and associated topics, gets a good airing done to death on the Cyling UK forum - there's a wide difference of opinion - for instance, I'd say cyclists who ride in black (and living near a popular cycling route, I've seen many) are asking...

I've been following this thread with great interest as my own 36v 10Ah bottle battery has been suffering from the ocassional power failure. The battery came from PSW Power and is silver in colour but otherwise looks much the same as the black case one in the Yose Power link posted by the OP My...

Hi Neal - I've just opened up the Java configurator for the OSF and in the 'battery cells number' box, the pop-up indicates that you can enter 14 for a 52v battery. The motor type (36v or 48v) is a separate setting but seeing as I dont' have a 48v motor nor a 52v battery, I'm not able to test...

For what it may be worth, I'm going to throw in my 6-penny's worth: My rig is a TSDZ2 250w with a VLCD6 display (no voltage readout, just fairly useless charge indicator bars) and a 36v 10Ah bottle battery After about 900 miles of use, I had the odd power shut down Faffed around a bit trying to...

I've just been reading several technical accounts/websites regarding charging in low temperatures and it seems that charging say at zero degC or lower, can damage the battery irreversibly which on subsequent charging could lead to problems. If this is the case then anyone with any brand Lithium...

Hi @Les186 , When you are peddaling and the motor is running under power then: 1. you will hear the motor 2. when you stop pedalling, the chainring 'runs on' for a few chainlinks due to the power tapering off - you can see this phenominon in the UT clip here. Conversely if the motor IS NOT being...

Jeez, I qiah the poor fella a good recovery - you don't have to be doing anything outrageous to have a bad injury - a freind of mine nearly lost a foot after simply loosing the bike over a dropped road verge and putting their foot down in an awkward way - it took 6 months for a 90% recovery -...

There's a useful post HERE about installing a temperature sensor - I'm reading it in earnest given the doubts expressed by Neal about overheating :cool: . Looking through that thread, I just might buy myself some of those temperature sensing labels from RS Components (link) to see what is going...

Hi Neal - I thought I read in one of your earlier posts that you were considering a TSDZ2 and I was wondering if the above are your own observations or those of others? Having fitted my own TSDZ2 in the Autumn, I've yet to ride in warm weather and therefore don't have any experience of the...

Probelm Solved (Apparently) I took the top and bottom sections off the bottle battery and established that the the 2 thin wires on the power on/off switch in the bottom section went to the BMS in the top section of the battery. The wires were on a plug/socket on the BMS to it was relatively...

3000km on a 750w motor and I'm guessing no maintenance such as a bit of a strip-down and re-grease (hence the seized Allen bolts). It's arguable whether that sort of maintenance should be needed, but from other forums and youtube, regular checking for grease, worn gearing and bearings looks to...

Out of interest, why did you change to a brass gear - was the blue one knackered? If it was, how many miles had you done? What power/voltage is your motor BTW? The brass gear is reported by many as being noisier. Some also think that keeping the blue gear is a safety feature (as like a fuse is...

Looking at this Endless Sphere post HERE, it is said that their are two controller versions in circulation (referred to as OLD and NEW) with the comment that the NEW controller does not work with OSF. Maybe the German forum member's problem was because of this? Anyway, it is something to be...

True enough but I went for the vlcd6 and no brake option which is provided with a 6 pin cable between controller and display and you need the 8 pin cable for an ebrake. I'm very comfortable without an ebrake and I certainly didn't want any more cables on the handlebars. I've now done 1500 km...

Thanks @wheeliepete - that link is now safely book-marked in the event that the BMS in my battery subsequently causes me problems. I will indeed be living with the issue - it's a strange one. What brought my comment about using a 4 amp charger rather than the supplied 2 amp one, was a comment...

Bump - anyone any ideas please? If required, where would I start looking for a replacement BMS. Thanks in anticipation.
