Help! What COMPLETELY LEGAL Ebike will get me up hills?

[Bike & Tina Turner]

My previous post was deleted despite editing out offending info, so I'll post my request again. Need bike, need to go up hill. Help, etc.

• I'm 65kg, 5'3"
• Hills
• £2k budget
• Have existing 26" mountain bike I can convert but quite an old bike with rim gears

I'd appreciate some genuine advice. Thank you.
