Unless you are a professional rider, then there’s really no need for you to go for electronic shifting, unless it’s just an irresistible feature that you can’t go without. The most high-end road bicycles nowadays have multiple gears in the front and even more on the back wheel. For a beginning rider to get an electronic gear shifting bike would simply be splurging, and getting a mechanically shifting road bike would work out better price-wise. You should probably instead use that extra money for other more important features, such as better brakes, more durable tires, or a more comfortable seat.
