i saw the click episode about it - it has a 4kw motor. I took some inspiration from Sheldon Brown (who very long ago converted a Raleigh twenty for off-road use - because of its very strong rigid frame) because I had an old Raleigh 20 - put a £208 BPM kit from BMS (with a 50 A controller) and suspension forks on it - it produces about 3kw with HK lipos and cost about £400 altogether. For sure its not military grade (it may be Chinese military grade) - but there's no way that cost even 5% of 25k to build
