trapezeartist Posted October 11 Report Share Posted October 11 I've just bought an ex-school 2023 ePure Race from Inch Perfect. It looks beautiful and I'm generally very happy with it, but like any secondhand (or even new) bike there are one or two things to sort out. I'm not impressed with the way the TKO switch is mounted. It's awkwardly inaccessible and is mounted on a curved bit of frame tube so it doesn't fit well. As a consequence mud and water can get into the back of the switch, which has happened. I'm thinking of putting it on the handlebars instead. Has anyone else tried that? It would require a two wire extension about 1 metre long (I haven't measured it yet) with male and female connectors. I can find pre-wired connectors with short tails which I could use but that would entail soldering in a section in the middle which I would like to avoid if possible. Any ideas where I could get a pre-made extension? Quote Link to comment Share on other sites More sharing options...
konrad Posted October 11 Report Share Posted October 11 Search "jwpf extension cable." AliExpress would seem the most likely source for a single cable. Are you sure the TKO function can be switched in real-time? Maybe EM put the switch where it is because the controller only senses its state at boot-up or when the mode is changed? I don't know. But yeah, it does seem like a horrible place for the switch itself. Quote Link to comment Share on other sites More sharing options...
trapezeartist Posted October 14 Author Report Share Posted October 14 Thanks konrad. I tried that search and the only doubled-ended male-to-female cables are from AliExpress, and they are only 20cm long. I haven't measured yet but I need about 1 metre. The pre-wired connectors are on order so that is likely to be the route I go. While I'm waiting for the postman to walk all the way from China I will look out for a suitable IP-rated switch that could be mounted in the under-seat position as an alternative solution. I don't know if the TKO switch will function on the move. I hadn't considered it before but it offers an intriguing possibility if it does. My main objection is the fact that a switch designed to be mounted on a straight bit of tube is mounted on a bend, so mud and water can get into the back of the switch.

trapezeartist Posted October 17 Author Report Share Posted October 17 I've just bought this switch off eBay. It's a CNC aluminium body and "waterproof" (though without any IPxx rating), and it cost just £4 inc postage. It is so much better quality than the OE switch. The handlebar attachment is very narrow so it may go onto the straight bit of frame tube under the seat. If that's not suitable I'll mount it on the handlebar.

trapezeartist Posted November 1 Author Report Share Posted November 1 (edited) The switch didn't fit nicely under the seat because it is designed to mount on a 7/8 handlebar. So I've put it up beside the throttle. Total cost for switch, plug and a bit of wire was just over £9 from eBay, plus some time to solder and heat shrink the three elements together. For comparison, the OE switch from Inch Perfect (not nearly such good quality) is £52.99.
