Currently have a EBC Model R with 500w rear hub. Was thinking of getting a Rize RX to add to the small fleet. Anybody regret going from rear hub to a mid drive? Are they slower or more sluggish off the line? Are they more or less maintenance. Just general street riding live in Vegas and it is a valley so there are some grades and to deal with but noting extreme. I am a big guy and need a big bike 6'-2" and 300. Anything else to look at with a max of $3600 or so. I know there could be some issues with Rize in general as far as not good support. Also looking at the Soul Sonic Saber Pro but it is a rear hub as well. Are Mid drives mainly for MTB and hill climbing?
