Question:
Trying to find a roof style rack for my new Ebike, an Aventon Pace500.3. The rack I have consists of two 1inch round steel bars mounted on top of my pop-up camper see picture. The bars are 42-5/8inch apart. Without the battery and seat, the bike weighs 44 lbs. Other bike specs: Wheel base = 27.5 Tire width = 2.1 Wheel diam = 27.5 Down tube diameter = 4.5inch vertically 2.5inch laterally I would like either a frame or wheel mount. The spread of my cross bars seems to limit the options I have. The Rocky Mounts MachTen might work, but the specs do not list a maximum crossbar spread. Do you have this info ? What rack options would you recommend ?

Hey Chris, thanks for all the information! For your Aventon Pace 500.3, I recommend the Kuat Piston SR Roof Bike Rack for 1 Bike - Wheel Mount item # KU32VR. This wheel mount bike rack has a 67 lbs capacity and fits crossbar spreads from 25" - 51". It will work perfectly with your 27.5" diameter 2.1" wide wheels. The carrier weighs only 23 lbs and measures 59-1/2" long x 4-15/16" wide x 3-7/8" tall.
Additionally, the RockyMounts MachTen Roof Bike Rack for 1 Bike item # RKY97MR fits crossbars 16" - 42".
Is that a trailer or a camper shell in your picture?
