BBC Breakfast item today on illegally modded ebikes

[Chris S]

Back in the 70's loads of us had 'field bikes', generally mopeds or small capacity motorbikes that we rode around farm lanes or the local quarry*.
These high powered e-bikes just seem a new version of this, no doubt 'older folks' were just as pished off by us back then.

* even Allan Millyard did it but being him he grafted a Mini 850 engine into a BSA Bantam frame..............by his own account it was lethal.

A Mini 850 engine wouldn't fit into a Bantam frame. And why use an 850? The 1275 uses the same block put provides a lot more power.

Forgive me for being dumb, but why all this fuss/paperwork for a throttle on a legal ebike?

I had a legal e-bike in 2011ish and it had a throttle. I never used it. I always had e-assist on Max setting. If it's legal (250W and limited to 25km/h) then the presence of a throttle does not make any difference. Even on the flat, you can go faster pedalling than you can with WOT. Downhill, irrelevant, you'd cruise at over 15mph so e-assist deactivated. Uphill, combination of e-assist and pedalling so no need for throttle. And it wouldn't be comfy standing up and trying to hold a twist type throttle anyway. Throttle only up a hill = lucky to go 4mph if it'll even get up.

Either my £1500 Wisper was especially weak, or these newer legal bikes put out a lot more torque for their 250W power

I had a throttle on my first ebike - got it in 2011 and it was used then
They were legal on bikes made before 2016 - but the power was also lower - 200W - but mine was actually only 180W

As you say - I hardly ever used it
did find it useful for starting up sometime - especially if I stopped quickly and was in the wrong gear
but main thing I miss about it is going up very steep gravel or soil slopes on paths - it was very useful to have access to the power to help get the bike up

but it is not at all useful

The only argument I would have against it would be for people of less that ideal mobility
If I was able to I would rather have an ebike as a mobility device that a scooter before I need to have a proper one!

Border Force with plod back up do fairly regular sweeps of the delivery riders amassed around McDs etc around here...many overstayers, 'pretend students' on visas, asylum seekers, others with no legal right to work. Apparently the delivery companies got a dressing down at the home office recently about not doing frequent (ie at least weekly) checks on their riders right to work. They promised to be more compliant... hmmm yeah [having to go to Croydon was probably worse than the meeting itself]

They are all over Plymouth; 80% delivery riders, 10% masked youths and 10% middle aged men who don't want to fork out for a CBT and get legal. The delivery riders are mostly clueless but not what I'd call reckless. Those deliveroo riders who use 125 scoots are also shocking, I had following me on my scoot in a bus lane as I was slowing down for a light, he undertook me and ran through the red.

This is Allan Millyard we're talking about, the mini engine came from a scrap car in his parents garden and the bantam engine blew up and I think he was 14-15 when he did it, certainly before he got a road legal motorbike and don't forget he's old enough not to have been saddled with a restricted 'slowped'.............bit of work and a gearing change and most mopeds at the time would pull 60mph easy.

This is Allan Millyard we're talking about

Who the fook is he?

Who the fook is he?

He's the nutcase highly qualified engineer who built a bike out of a 7 litre Dodge Viper V10 engine, he has also constructed many 4-5 and 6 cylinder Kawasaki 2 strokes and a few V12 4 stroke Kawasaki bikes from the 6 cylinder ones. He also built the 'Flying Millyard' a 5 litre V twin with cylinders from an aero engine after a conversation with Steve Parrish when he won a prize for his 100cc Honda V twin saying "well I won a prize for the smallest V-twin now I'm gonna build the biggest".

Tap his name into google and marvel at his creations, all look like 'factory bikes'.Oh he built a downhill MTB or 2 for his son with enclosed gearing and chaincase that acted as a swinging arm
