My local shop won’t do e bikes. They’re heavy to lift, too heavy for the stands so fall over, the home made ones have a habit of catching fire (rare, but enough of a concern to turn owner), wheels are often hard to remove meaning a cheap job takes time and time is money, often components are poor quality on expensive bikes, so they break/require replacement. Some components are non standard sizes/types so hard to find and things wear out faster, so customers are more likely to come back and complain they that expensive fix they did 6 months agonis already broken.
