Some of the springers get wore out over time and will give you a high speed wabble. Then there’s the cool looking suspension forks but these front hubs have so much torque they bust the drop outs. These hubs are very easy to install. I like using the triple tree $100 forks. I’ve never tried the rear hub yet but installing one one the kids bike. It’s said to be more of a natural feel. The mid motor (crank)ones are the most reliable. There’s been so much technology done that’s why their twice the price. The bafang HD one you can run all day wide open but the down fall is when you replace the chain you have or should replace the sprockets too. The up side is you can use multiple gears hehe the rear hub one as soon as you touch the throttle none the gears make any difference other than for pedaling. I chose electric over gas engines as soon as I heard that you can only use the gas ones for 10-15 minutes before you have to park them and wait for them to cool down. I love the smell of 2-stroke engines reminds me of winter time snowmobiling
