    Using BB motor like GSM or BBS as intermediate drive

    Dear all, I've not been on here for a while - as I went through a foolish phase of trying to ride my heavy aluminium recumbent (velomobile) without e-assist. I've seen the error of my ways, so may lurk a little more frequently again... One of the things I am wondering about is using a crank...

    Quiet charger for 36V battery

    Dear all, I have a 36V 20Ah battery which is still working (bought from BMSb a few years ago). I got 2 chargers with it, which both deliver approximately 2.5A at 36V (or 42V as it appears to be). They work well, but are very noisy - the small onboard fan spins up an creates quite a noise. The...

    KT controllers - KT-LCD6 now displays cadence

    Hi all, I was looking for a replacement display for my trusty KT-LCD3 (also labelled by BMS Battery as an S-LCD3) as the control button casing has split, and the display is a little wide for the current location. I noticed that the new generation includes LCD6 - which is in a portrait...

    LED light strips - wire in parallel, not series

    Hi all, I made an interesting discovery over the weekend. I'm using multiple LED strips on my velomobile build (white at the front, red at the rear, amber for indicators) and was getting all sorts of strange problems (some not working, some being dimmer than usual). The strips I used are...

    Combined indicators & hazards - from single flash relay

    Hi all, I'm slowly working away on a velomobile (based on an Alligt Alleweder A4 for those who are interested) and am adding lights. I have indicators working well (as when the tonneau cover is on there is little space for indicating with your arms), and wanted to use the same flash relay to...

    Combined light switches for motorbikes - internal wiring issues

    Hi all, I spent 2 fruitless days trying to trace faults with my indicator circuit. Cutting a long story short, the fault was eventually traced to the internal wiring of the switch I was using - some of the internal cables had their insulation cut back too far, and when the housing was pressed...

    Brake sensor (3 wire, Hall?) - operating the wrong way round

    Hi all, I've got another naive question for the collective wisdom on this board. I have extended a brake sensor cable (fitting into a recumbent velomobile, and the cable run was too long without extending). All seems good, except that the brake sensor only cuts the motor out (showing a brake...

    GSM / S12S / LCD3 / 36V - error code 03-INFO

    Hi all I've got some issues with setting up my GSM crank drive motor - almost certainly down to my ignorance. Tony from Woosh has already been very helpful with other questions that I had. All is connected apart from the speed sensor (I have to extend the cable). Unfortunately, I now have an...

    GSM with external controller - PAS connections

    Hi all I bought a GSM crank drive from Woosh months ago, and have just got round to trying to fit it to my velomobile. I have modified my controller (S12S) to deliver max 18A (desoldered and filed shunt). However, the 'pedelec sensor' lead with the GSM has 4 wires on the connector (black...

    Using rear geared hub as mid-drive - feasible, or a bad idea?

    Hi all, Questions at the bottom for those with little time. I had a bad spill a few weeks ago - smashed my collarbone into multiple pieces, and have been laid up recovering for several weeks. Unfortunately my lovely wife has therefore decided that cycling is dangerous. I'm considering using it...

    In-line brake sensors - how to stop them moving?

    Hi all, My commute includes some pretty poor roads so lots of bumping up and down. Sometimes the brake sensors move and cause the controller to cut out. Currently I've been using cable ties but these tend to move after a while. Any other ideas? Thanks Phil

    Bullet connectors for motor phase wires

    Hi all, After many happy miles I've had some issues which I eventually (by the side of the road in the rain) managed to trace to the bullet connectors giving up. What have others done? Change to other connectors or just cut off the connectors, solder and heat shrink? Is it ok to do the same...

    Broken spoke - what sort of nipples do others use?

    Hi all, Much to my annoyance I wheeled the bike out after a lazy winter and discovered a broken spoke on the rear wheel (Bafang CST). It broke just at the elbow. I did order spare spokes so that is OK, but am a bit suspicious of the alloy nipples that came from BMS battery. In the original...

    Misc spares for sale - thumb & half throttles, brake sensor, motor ext. cable, connectors

    Hi all, I've not been on this forum for a while - winter = icy roads and a far too convincing excuse not to cycle for a lazy person like me. I've finally cleared out the study and have some excess spares that I no longer need (I bought extras from BMS battery but fortunately ended up not...

    Winter battery care - how to look after battery when not in use for a few months

    Hi all, I've been enjoying commuting to work a couple of times a week on the ebike - the combination of a 36V 20Ah battery in the frame and beefy CST rear hub mean that hills and headwinds are no longer such a problem ;) The icy weather appears to be on us, and roads are getting a bit...

    S12S controller - removal of solder from shunt, now motor does not run

    Hi all, I've made a foolish blunder. On measuring current to the S12S I discovered that I'd been allowing up to 32A due to getting a little exuberant with adding solder to the shunt. I therefore decided to remove a little solder using a soldering iron and solder sucker, and also decided to use...

    Speakers on an ebike - any thoughts?

    Hi all, I'm not a fan of wearing headphones while cycling as I quite like to hear what is coming when going slowly, and be able to turn my head to hear what is coming when going faster. However, now that the bike is going OK I'm beginning to wonder about adding more gadgets (!) Has anyone put...

    Anderson powerpole connectors on BMS battery shrink wrap battery & S12S controller

    Dear all, A bit of a newbie question here again I'm afraid. I want to pop in a watt meter temporarily between battery & controller as although I have the LCD3 that shows power, I soldered the shunt so it no longer shows the correct amount! The kit came pre-wired with Anderson powerpoles for the...

    Current control or speed control?

    Hi all I have the S12S controller from BMS battery and have been riding with current control (so the different power levels assist up to a max current whatever your speed). This is working nicely, but I find that I tend to just keep putting more effort in and going faster. Do others tend to use...

    Power output limited by battery?

    Hi all I had my first long run on the conversion today to work and back (39 mile round trip, lots of hills). It went great, but I'm still seeing less power output than d8veh suggested I should 500W CST kit with S12S with soldered shunt and 20 Ah 36V shrink wrap battery from BMS battery...
