I had an engineer colleague who rigged his own mountain bike. From memory the battery was attached to a pannier. Claimed top speed of over 60kmph. I thought he was telling porkies until I saw him BLAZING around richmond park
There's a guy at my work that prides himself on his DIY ebikes, dude gave me a lift back from the pub once on his pannier rack and it was terrifying. I've ridden slower motorbikes
