My wife and I opted not to get the fenders when we originally purchased our City 2 ebikes. What a mistake that was! These fenders are AWESOME! A nice heavy weight and a great black finish, add the PURR-fect finished look to the City 2. With both of us being over age 65, we're mostly 'fair weather' riders, but we always had to clean a considerable amount of dust and dirt off of the bikes after our favorite 26 mile trek for breakfast; through the woods on our favorite bike trail. These fenders have cut down on that chore considerably!
As far as the assembly goes, it's pretty simple. The tools that come with your Denago, and maybe a 10mm wrench, are all you'll need for this project; with one SLIGHT adaptation. I'll get to that in a moment. Slip the front fender through forks from the BACK. The rear fender goes from the top, forward. The longer cap screws will be used to mount everything to the frame and front forks. The front fork mounting points will have screws in them that need to be removed, but will NOT be reused. Use the cap screws. The round headed screws will be used to connect the brackets to the underside of the fenders and then the support arms to the brackets. Loosely fit everything together. Now, the adaptation. At the bottom of the rear fender, where it mounts to the frame, I used a round headed screw. I didn't like the idea of a larger cap screw 'staring' back towards the tire. The screw is a much lower profile. To accomplish this, I cut down one of the appropriate hex wrenches, that came with the bike, to fit between the fender and tire. No need to deflate the tire or remove the wheel. There's not a lot of room to swing the wrench, BUT with a little patience, some friendly chit-chat or radio and some coffee (most definitely coffee), you'll get it !! One last look at everything and then you can start snugging everything up.(this is a good time to have more coffee) You can align the fenders perfectly by adjusting the screws where the support arms attach to the fender brackets. There's some wiggle room to do so.
The last thing to do? Step back, admire your 'new' bike and have a 'job well done' cup of coffee! Oh yeah!
