I'm curious, how many repairs do you do in a week or month? and how many of those are cheap e-bikes?
What are the most common repairs that you perform on cheap e-bikes?
How many of cheap e-bike users that have zero problems come to you?
How many "better brand" e-bikes have you sold in the last 12 months?
How many "warranty" issues vs regular repairs have you had with "better brand" e-bikes in the last 12 months?
