So it looks like it's not limited to £1000 anymore and can basically be any bike from any vendor?
They're claiming that there never was an overall cap of £1000 (this is in direct contradiction to previous guidance given over the last 20 years).
They're saying that the cap only ever applied to small bike shops. FCA-authorised bike shops can loan bikes, including e-bikes, worth over £1000.
So no, it's not quite any bike from any vendor.
It's any bike under £1000 from any vendor (that participates in the scheme); or any bike or e-bike of any value, from an FCA-authorised provider.
HMRC have generally assumed the bike's value at the end of the loan period to be zero, so you get the bike at the end of the loan, for free, rather than having to buy it (from take-home pay) for its resale value from your employer.
However, that's not a written rule. It's just the way it's been done to date. Bikes that do have a significant resale value when aged 5 or so (e.g. Bromptons) are potentially at risk from HMRC. Discuss this with your accountant.
Incidental note: electric two-wheelers are the most popular roadworthy electric passenger vehicle in the world: about 1 in 17 people in the Netherlands has one; and one in 7 people in China has one. (and that's a
lot of e-bikes and e-mopeds).
