The course isn't anything to do with me. I just added it as I couldn't see much using the search button about learning the basics of the science behind ebikes. I did see a Udemy course I liked called: "crash course in electronics and PCB design" I would have done that but the software used to simulate pcb building doesn't work on a Mac. https://www.udemy.com/course/crash-course-electronics-and-pcb-design/

I've been trying to learn a little more as my knowledge on, say, what a mosfet is is zeroo_O. After grinding my way through some youtube vids I came across the free OU course on introducing electronics. It's free to sign up. It says by the end you should be able to: recognise a variety of exciting high-tech products and systems enabled by electronics manipulate voltages, currents and resistances in electronic circuits demonstrate familiarity with basic electronic components and use them to design simple electronic circuits see how signals can be represented in the time and frequency domains for Fourier analysis record, analyse and filter audio signals to improve their fidelity. Have only just started it so can't comment on how relevant it is to ebikes. This is more by way of a heads up if anyone else is interested. Would be happy to hear of anything similar that people have found to increase their knowledge of how this stuff works. https://www.open.edu/openlearn/science-maths-technology/introduction-electronics/content-section-0?intro=1

You can add me, I'm in Darlington

Nice story! Thanks for sharing. Interesting to note that a battery with such a long time lying dead can still be brought back to life - if you’re lucky.

That's good to know. I'd never go back to having straight bars after having used these.

I used to carry the dog in a box on the front - I lived very rural then - when she moved about it felt twitchy so that's when I got the bars. They are long (710mm) and make it easy to keep things stable. The bars are Jones H bars. I like them a lot and find them comfortable and stable and like the easy change of hand positions. They were frighteningly expensive for a bit of bent tube but now there seems to be more options at more reasonable prices out there. Yes, I changed the stem, even though the bike is xl I wanted a bit more sit back which I find more comfortable. I also put big pedals on. Peddling innovations catalyst. So the arch of your foot sits over the centre of the peddle. I like the feel of cycling like this. Am aware that others think its just chucking your money away on a gimmick. You pays your money and takes your choice Cheers. Kevin

I know I was just looking through your site and saw that. Thanks for the heads up though so people realise.

Thanks for the heads up Andy, it's fair enough to put that information in the mix. You have a great weekend too. Kevin.

Thanks for that. Especially the info on what parameters make it run efficiently - and therefore not straining the kit - I'll spend more time finding out about that. I'd looked at woosh and their good record with customer service. They have no kits in till the end of July. I'm not in a rush though and these links and info are food for thought in the meantime.

Thanks for the add. I'm looking to convert my Ridgeback. I've been without a car before and just cycled as needed and am in the process of getting rid of my van and going back to doing the same now. I'd like the luxury though of some electric help. The bike is not light and carries shopping and stuff too and I'm 6' 3" and 225lbs. Work is around 6 miles each way. I'm looking for advice on a motor and battery configuration that could do low 20's for speed. I don't mind derestricting a regular (more expensive) set up or trying something out there from eBay. I'm hoping to find though something that is known to be reliable. I'd rather get it right - and spend more if I have to - first time, than put something together and shortly afterwards wish I'd researched more... any advice welcome.
