On london road I mostly see men injured on the side... they all try to squeeze on any small gap that make very dangerous. They also try to pass even when car driver slow down a bit for whatever reason.... However, these accident not involving lorries may not all be recorded as they are... sort...

The DIY battery pack working for almost a year now... It's not looking too bad. I had someone who told me it looks like a lady bag

Hello all, I don't know if it's related to how I use the handlebar or the nature of them or my position on the bike, but I have some carpal pain when I cycle: It is probably accentuated by the fact that at work it also doesn't rest my wrist... but I wonder if there something I can do for my...

You're back! I don't see you much these days.... i thought you had a new hobby :p

I didn't evade tax as I reported item value and will pay the right amount of VAT. Furthermore, the item I need isn't for sale here.... My problem isn't the tax.. it's the handling fee that is twice the VAT in this case.

I've got rid of all my lipo (zippy compact battery and cheap 4s turningy) more than a year ago and never regretted it. - no more spagetthi wiring - no more jst paralleling and cell log constant check - no more cutting all the plug from a new battery pack to connect to new ones - no more balance...

The welder do cost and I bought one.... But cell holder i don't use them anymore it takes too much space. I glue them with separator on cell group for chaffing risk. The strip does almost cost nothing once you get some. Like lipo, there is a cost to get started (lipo you need balance...
