Summary –
The bill creates a sales and use tax exemption for buyers of electric bicycles and related cycling equipment.

Details:
The exemption also applies to up to $200 of other cycling equipment, like a helmet or a bike lock. It expires on May 1st, 2025 or when $500,000 in sales have been exempted. (The bill declares the intention to extend the expiration date if the exemptions have produced at least a 25% increase in the number of electric bikes by the time it’s reviewed, which I think would be in ten years or less.)
