For my DIY, I wanted a light, practical, city bike, that was a stealth hidden electric. I also like old stuff so I wanted an actual old bike, not an old "style" bike.

I used a 1978 Raleigh steel frame, paired with a rear hub motor, and modern 700c deep alloy wheels, with 28mm tires. The battery and electrics are in a 1970s pannier bag with the original 6v lights run via voltage converter.

The electric hub came off a wrecked ebike and was originally made to run on 36v @7 amps, so made around 250w. I've smashed that up to 48v @13 amps, so it's now around 620w. This is good for 40kph, which is as fast as I can pedal anyways as its a single speed sprocket.

Originally when I did the conversion I ran a 36v 10ah (360wh) battery which gave me 50km range @22kph. My new battery is 48v 13ah (624wh) so now have a range of almost 90km. Original weight of the bike was 20kg, now its 27kg.
