You may struggle a bit for electric on Cyclescheme. There’s a limited choice and availability at that price point.
The retailer has to pay 10% or so, so they’re reluctant to provide Cyclescheme on any discounted bikes.
If you have the option for cash it’s well worth looking around you may get lucky and find a discounted bike that offers similar value to Cyclescheme benefit. I managed almost £1,000 off a previous year model.
Alternatively, watch
eBay, Gumtree, etc. A friend recently managed to get a nice less than year old Haibike for £1,500, (and in Glasgow).
Finally, if you know someone with a card, Costco does have ebikes around the price point from time to time. Quick look and they have a “Vitesse Beacon” at £1,200 at the moment. It looks like a hub drive so probably not as good as a centre drive (like Haibike). Hubs sometimes suffer on Glasgow’s and surrounding hills- but it’s probably fine.
