One which can be eliminated immediately is the Thule 990: My experience. I should have known from the specs: "Carries up to 2 bike (70 lbs Total)", and should have ignored the contrary recommendation.
From Thule, their 916 T2 (technical information)for 2" receiver (Arnie F has an older steel version), or 917 T2 for 1-1/4" receiver. Same features are listed for both models:
- No wheel removal, no frame contact.
- 4 Bike Ã¢â‚¬â€œ 2Ã¢â‚¬Â hitch, 2 Bike Ã¢â‚¬â€œ 1-1/4Ã¢â‚¬Â hitch.
- Folds up for storage and down for access!
- Fits a wide range of bikes.
- Carries bikes up to 60 lbs. (160 lbs. total - 4 Bike / 100lbs. Total - 2 Bike 1-14Ã¢â‚¬Â)
- Fits wheels 20Ã¢â‚¬Â-29Ã¢â‚¬Â and up to 3Ã¢â‚¬Â wide tires
- Accommodates bike with wheel bases up to 48"
- Locking accessory available.
- Thule One-KeyTM System Compatible.
My understanding (I sent an email to Thule asking to correct me if I'm wrong):
The 916 T2 (2" receiver) will be good for two 60 lb bikes, and stay within its 160 max limit ==> Max of 120 lb for 2 bikes, no more than 60 lb each.
The 917 T2 (1-1/4" receiver) could be good for two 60 lb bikes, but first encounters the 100 lb max limit ==> Max of 100 lb for 2 bikes, no more than 60 lb each.
So in both cases, they are not suited for carrying a pair of 75 lb ebikes (not even one actually).
Conclusion: Fails to meet the goal of carrying two 75 lb ebikes: Limited to a pair of 50 lb bikes (1-1/4" receiver) or pair of 60 lb bikes (2" receiver).
