This Swytch kit is very good! I did a lot of big changes for my customized triathlon bike (I call it Outroad SFDP 18 or Outroad SF Lightning II). 250 watt motor power is good and I mostly paddle assist more than throttle while it is used for backup. My project of this bike took me days to change out the brake lever (expensive Dura Ace), disc brake for heat dissipation, 5000 continental race tires, Redshift pedal lights, customized time trial handlebars for uniqueness, stronger adjustable kickstand, USS seat post for shock resistance, better soft racing seat, black wheel spokes with black rim Weinmann DP18. With the additions, 2 headlights (This one is out of stock), tail lights with double lasers on side, X GPS offline technology, mechanical portable air pump, portable & foldable locker, rockbros bag, and double cup holders on the rear seat. This whole thing cost me around $2000. The wheel spokes took me 4 days to finished if learned for the first time. Otherwise, the kit was pretty easy to install, the pedal sensor works flawlessly, the throttle works great and the OLED full control but my time trial handlebar has no room for them so I find another way to put them on by buying and using the handlebar extenders in the front. The customer service response is good! the delivery is okay but I did receive a refund for promise shipping delivery date (You deserve my 5 star rating for that and did an excellent job), the price is just right! Thank you Swytch Team!
