Has anyone had success installing fenders on their Q-45? If so, what brand/model did you buy?
Fenders for a Q-45
- Thread starter GoldenEyeDave
- Start date
I was at my fourth bike shop, before I found some that were as wide as the stock 1.75” tires, but would fit between the front fork legs. I think they are Evo brand. What the Q45 really needs is two rear fenders.

Yup. Two rear fenders. You want the one on the front wheel to come forward enough so water doesn't spray onto your chain and chainring.
Fortunately there is a shop here with large bins of secondhand parts. I got these for $5 each.
Photos attached of my handmade mounting brackets. Both wheels need them at the front of each. The rear wheel was straightforward, the front trickier. It's attached to the mounting hole by the BB by a strip of aluminum, painted black. And it has the disadvantage that it must be unscrewed to adjust the boom (hence the wingnut).
It's a bit hard to see, but I strengthened the rear fender with a strip of aluminum on the inside of the fender. Note the 4 screws on the top of the fender, and the end of the strip is also screwed into the mounting bracket.
These polycarbonate fenders break pretty easily - I experienced this on my Q2 - so the strip helps.

Your front mudguard is IMHO too high. I would put it closer to tire.
My front mount, on the front fender allows a few cm of boom adjustment, before I need to move it to the next hole in the fender.
Your four point mounted, reinforced fender, should to the trick. I'll take a bit more time to make a better bridge, for the front of mine and add another pair of more vertical stays. I don't think I'll go so far as to reinforce the fender, as you did.
Yes, mine is rather far from the tire too. I'll need to extend the fender's fork clip, to get it lower.

My too-far front fender is forced by:
- The mounting bracket at the fork crown
- Wedging it between the arms of the chainstay at the front (for extra stability)
I probably could fashion a longer mount at the fork crown ...
@onmyback , it's very easy to get a thin strip of aluminum and screw it on the underside of the fender, then into the mounting bracket.
Somehow, the rattling on our crappy streets broke two sets of rear fenders on my Q2 before I figured this out. They both broke right at the bracket. I think the bracket mount is strong while the mounting rods allow wiggle and bounce, stressing it right at the bracket and eventually breaking it.

Thanks Everyone! This thread has been very helpful.

Well done! That looks like it will do the job! Thank you for sharing the 7000 word essay in 7 picture form!
Completely unrelated to fenders, but noticed from the pictures, I had waterbottles mounted under the seat on my QX100 and lost one, not even on that bumpy of roads - it was within 6km of riding on paved roads most of which are newly paved, just the occasional bump and one storm drain and it worked itself loose. My friend found it on the way back and I kept my hand checking it continually on the return journey and it definitely was constantly vibrating looser. You might have a better cage for this, but just thought I'd pass on my recently acquired hindsight.
Do you have more pictures of your ride on another thread? If not, could you? I would love to see what else you have done in your build. It looks great in your avatar.

I wrap the bottle with silicone wristbands so that the added friction will keep the bottle in place.
I had thought I might need to add a front derauler, but had only thought of a double ring. In practice I find I can climb my steepest hills, and can pedal up to the low 40kmh range, at maximum cadence. I see you went directly to a mountain style triple.
Did you find your rear fork/swingarm, was much too narrow?

I have triple setup across all my bikes cos I like to have very low gear available for climbing steep to very steep hills.
The rear fork is much too narrow and I did try to open it up a bit but without much success. I think it is a manufacturing error.
Maybe a little late for the fenders party but this is my solution
Use 2 rear 26" Planet Bike Hardcore Recumbent fender, for both front and back wheel.
To attache to the frame I used aluminum Bike Number Plate holders. I got cheep ones from Ali but it is similar to these from Amazon.
For the rear fender I used 2 holders.
For the front I made a new hole so I could add a bolt. I haven't cut the edge yet so I guess its not very esthetic.
This was very easy to setup and I didn't need to make any custom fittings or use spacial tools. Even the additional hole on the front fender was easy to make by heating a screw on a flame!
Hope this helps

I like your reuse of brackets, as fender brackets.

As I live in the driest State, of the driest Continent, South Australia, we do not see much rain, except drizzle from our Spring time of Oct to November, so I only use BBB Road Protector mudguards, which can be removed using one lever, when no rain, OR the rear mudguard, when removing the rear wheel to fit the S30 in the back of a i30 hatch.

I have noticed that riders in England, and Seattle, where heavy rain does occur REGULARLY, that they have mudguards in front of the front fork.
What does this section of mudguard stop water getting onto?
