Just a thought - i’ve finally got my e-bike going (been an ongoing project for >1 year!) but was wondering if any other members would be interested it a meet up/natter… I know there is some interest in e-bikes and Ive seen an e-scooter in the space. Anyone fancy comparing bikes/notes over a coffee ?

Sounds good to me!
What are you riding?
I converted an old GT Arrowhead with a Bafang BB02b.
anyone know what is the current position on legality is …i.e according to the road traffic act etc … are they permitted on a public highway, on the pavement what are the restrictions and insurance implications ?
Electric bicycles are not permitted on pavements because bicycles are not permitted on pavements.
To be classified as an ebike or pedelec and go anywhere a bicycle can go the power must not exceed 250W andthe motor must not provide assistance over 15.5mph (25kph). The rider must be over 14. It can have a full throttle if bought before 2016. If after the throttle must stop assisting without pedalling at 6kph. Exceed these and the bike is private road or off-road only.
Electric scooters are not allowed anywhere.
Mine is a Saracen hard tail and I’ve used a few bits but the motor-wheel/esc is a Voilmart 1500w kit. Battery is a 54v 13,000mah. Got a power analyser/logger in circuit too so I can see what the system is doing.
I have a combination of twist throttle and pedal assist. Bit of a beast in full loony mode (>35mph) but can be switched to 250w street legal mode.

I have a general DC one used for projects just like this (+ solar and power wall types too). It’s 5v to 60v compatible which is important for ebikes (the radio control ones don’t always have the high enough rating)
This is the same one I have Link
Cool, that looks like a Cycle Analyst. I see you’re using a six MOSFET controller 
What’s that enclosure in front of it attached to the top tube? Is it for cabling?
Yes, just for cabling at this point. Planning to use it for a GPS/GSM type logger module as some point too…
Cycle Analysis looks good ! Will have a better look on my desktop later

Presuming a weekend would suit, but feel free to add any dates to the above.
Anyone got experience with decent bike computers? Mainly from an anti-theft / tracking point of view?
Everything ive seen online either has terrible reviews, or relies on a cloud service which has already gone bankrupt.
Thinking of hacking something together myself
I’ve been working on something that satisfies those requirements since my last bike was stolen. You can check out an incomplete overview of it here: http://bit.ly/2IZX31y , there has been a bit of feature creep since.
Yep. 2 * Pis (Pi cam on each for AI) 4 ESP32s (one for the removable LCD, one for each set of wheel lights, one on the frame for telemetry) and a Teensy for power and LED control. The idea is for it to be modular, the minimal setup is just the pi and teensy.
For me it would have to be a Saturday or Sunday afternoon really. is that OK ?
