I'm with AHicks here. While I'm not one for knowingly breaking the law, I've also spent 2 seasons riding over 2K miles with my class 2 bike on trails in 6 states which may or may not be class 1 only. In most cases, posted signs aren't clear on the issue.
When trail riding with my class 2 bike in MA. last season, I stopped at a LBS who rents class 2 ebikes to ask about local laws. The owner told me that technically, class 2 bikes are not permitted on MA. trails but compliance isn't strictly enforced. He told me that local LEO's look for right side split grip twist throttles to spot class 2 & 3 ebikes. He showed me this left hand thumb throttle he plans to put on his class 2 rental bikes if enforcement becomes an issue:

The short right hand grip and throttle would then be replaced with a full size grip as mentioned above. The left thumb throttle is much more stealthy and easier to disguise. He says a great many of his customers are retired or elderly folks who require a throttle to ride safely. Otherwise, he would simply remove the throttles completely.
I can't say I approve of his approach but he is a small mom & pop LBS with a LOT of $$ invested in a fleet of class 2 bikes. When he purchased them, the class laws had not yet been adopted in MA. I suppose I would do the same thing if I were in his shoes.
It remains to be seen if I'll do something similar. It will depend on whether I actually get cited for a violation. In the mean time, I'll continue to ride courteously, not offend others and use the throttle sparingly and only when necessary.
