All the details on Kellys new 2021 Theos F Series eMTBs.
Last week, we took a look at some details about Kellys new Theos F Series eMTBs. They are big, burly, and had a new Shimano motor in them and new construciton techniques. And now that Shimano have released the full details of their new EP8 motor to the world, the full details of Kellys big and burly eMTBs has been unveiled.
What is really interesting is the production technique called Feather. which is a thermoplastic hybrid carbon steel composite. Resin has become the weak point in carbon fiber, especially for impact damage, and this material has a 200% increase in strength and impact resistance. Which sounds perfect for mountain biking! The material can also be recycled, which hasn't been talked about much, but that's a big deal.
What's also a big deal is the battery. The Kellys Recharge Li-Ion battery has a whopping 720Wh, and uses an easy system to mount and release the battery inside the frame. It slides out at the base of the downtube, meaning you don't need a massive hole in the downtube.
Kellys Theos F Series F90 Super Enduro
This is the big one, the top dog. This is the bike you put at the top of your wishlist, and work hard for! Selling at $12999, the bikes come in two sizes, medium or large.
The frame has 170mm of travel, controlled via a Fox Float X2 Factory shock. There is a Fox 38 Factory with a GRIP2 damper and 180mm up front. Interestingly, the drivetrain remains with Shimano XT Di2 11-speed. It's smooth and super fast, so there's no complaints there!
Brakes are Shimano M8120, so the 4-piston trail brakes, and DT Swiss provide wheels with their H1700 wheel set. These are the eMTB specific wheels, nice and wide with a Star Ratchet engagement. They're wrapped in Schwalbe Eddy Current eMTB tyres, with a 29x2.6" front and 27.5x2.8" in the back.
Kellys Theos F Series F70 Super Enduro
This one is just as much bike, but with a different spec on the same frame and motor, to keep $3000 in your pocket. As such, it comes in at $9999. You get a Shimano Deore 12-speed group set, and a sweet RockShox ZEB fork on the front end, delivering 180mm of jank destroying suspension.
The shock is. a RockShox Super Deluxe Select Coil R, which will be managing your 170mm of travel. Brakes are Shimano MT420 4-piston brakes, and the hubs are Shimano, laced to wide alloy rims and wrapped with Schwalbe Eddy Current eMTB tyres in the mullet combination.
Kellys Theos F Series F50
Also on the way is the Kellys Theos F50. This bike drops the travel to 150mm at the front and 140mm in the back. It still has the Shimano EP8 system and 720Wh battery, and the overall same looking frame design.
The F50 sells for $8999, and the suspension package is a RockShox 35 Gold RL Debonair, and a RockShox Deluxe Select R. The drivetrain is a 10-speed Shimano Deore group set with 11-46 range, with 4-piston MT420 brakes. Rubber is taken care of by Schwalbe, with Nobby Nics in a mullet size option.
Sizing and geometry
As stated above, all bikes come in two sizes, medium or large. The F90 and F70 are a little slacker than the F50, with 64.5 degree head angles and 75 degree seat angles. The F50 gains half a degreee in both.
The wheelbases are long thanks to a long reach, and the chainstay length is also on the longer size. Bear in mind this will pay off for stability, which is probably what you're chasing if you're looking at the F90 and F70 inparticular.
These three bikes are all available to order via Ride Sports, and we are hoping to get one onf or tow of them for a review when they become available.
