Mudguards

I'm looking for recommendations for mudguards. We have ordered a Trets Trailer for my son and want to minimize the chance of any "muck" being thrown up at him while we ride. His regular Trek bicycle trailer has a netting cover that seems to do a great job keeping "muck" off him while we ride.

Initial test ride in front of the store:



My son Ryan has CP and we have been cycling with Ryan in a Trek Trailer with the Tandem. For about 1 year now we have been considering alternatives for the Trek trailer. There are bigger trailers for special needs kids but Ryan has the capability to pedal but cannot balance.

Hase has made a childs trailer for a few years now and after considerable research we decided to purchase the Hase Trets trailer. As a bonus, starting model year 2008, Hase modified their Trets trailer to be adaptable to a three wheel Delta Trike - This is a perfect solution to Ryan's cycling needs and much more practical and usable than all of the regular and special needs Trikes.

Two local dealers for Hase and following a brief phone conversation with the first dealer which did not go well, I contacted "Hoppy" at T-Ryx cycles in San Diego and we spent an afternoon testing the Trets and playing with the rest of the Recumbents. I fell in love with the Hase Kettwiesel Delta Trike and the Kettwiesel will replace a Tadpole trike which I sold last week. We expect the Hase Trets and Kettwiesel to be here in the next 1-3 weeks.

From an adaption perspective -
1. My current focus is to install fenders on the Tandem to minimize debris - I believe I can install a shield to the Trets but have not finalized a solution yet.
2. Install a pedal solution which will secure Ryan's feet to the pedals. Hase has a solution and I am researching local options.

Please feel free to email me at: redondobeach at mac dot com if you have any questions.

Regards Dwayne

Our tandem with 26" wheels has a set of SKS fenders I put on last year. Planet Bike sells a large variety of fenders. I have their fenders on my recumbent. You want a rear fender that goes down the back of the rear wheel as far as possible.

Add a mudflap to your rear fender. Like this.

Why? For this reason. BTW, the trailercycle has a similar mudflap because I used to tow a child trailer behind it.

I would really watch those forks being down that far. Those get stuck in the ground in a dip and it could spell disaster for the little guy. That is an awesome AWESOME set up though. Hats off!

Thanks! The test ride was very successful and the Trets is ordered. I plan to work a solution to remove the fork while leaving the bars on the bike.

SKS makes great quality fenders. We love them.

Like Michel suggests, you can get even better coverage by extending them lower.

I couldn't help but notice the trailer set up for your son, and it's amazing . I've been looking for a safe way to bring my son who has Cerebral Palsy (CP) on our rides in a way that he feels he is pedaling with us. I just read that you've ordered the trets conversion trailer. Would you mind posting your experience so far with this trailer, and your buying experience?

Thank You

You might consider putting a shield of some type on the trailer side to block debris just behind the wheel.
Something along the line of this

Thank you so much for the quick response and the great information. As soon as I saw your the Trets I thought it would be a great solution for our son Anthony. I have ordered a Cannondale Tandem and it should be here by Christmas. We are currently have a WIKE trailer, but Anthony is wanting to participate more. We are not sure if he can pedal, but we'll have to try. If you don't mind I may be emailing you with questions in the future.

Thank you again and regards,

Mario V.

Very good idea. Thank you very much for your input.

After you made this suggestion I saw on the Hase website, a picture with this solution in place:

The Trets is suitable for a child sized up to around 4' 11". Additionally the "adult" trike Hase Kettwiesel has an adjustable frame and additionally can be fitted with a child crank and I believe can be towed as well. Hase also has a great Tandem called a Pino and the front seat can be adapted for a child.


Child Hase Kettwiesel:


Tandem Hase Pino:


I like Trike recumbents and the Hase Bikes can be joined together to make Tandems and more (but long!!). The front seat of the Pino can be adapted for a child. Although I love the Pino, personally I have two issues with recumbent two wheelers or stoker kits:

1. I know my son does not have the skills to protect himself if he was using a stoker kit or on the front of a Pino and I dropped the bike. In the 7 years of riding Tandems I have almost gone down twice so I believe there is a chance I could drop a two wheel bike. I have gone down hard on my single bike in the last 7 years. I slid out on a corner with leaves.

2. With recumbent two wheelers, I have both met people in the Dallas Tandem DATES club and read about major hip and thigh damage when they dropped their bikes. If I drop a bike, I think I would rather break a collar bone than a hip 8( I admit I need to study more about the risk of injury and recumbents two wheelers.

I like the Pino and the Pino/Trets combo and assuming the risk of injury was the same as a diamond frame tandem, the Pino/Trets would be great for my family as is the Santana/Trets I have today.

Here is a website about a child with disabilities using a adapted Tandem Hase Pino:

...and for the Tandem "go fast" teams:

Dwayne,

Removal of the fork, but keeping the bars is a challenge. Forks and steerers are highly stressed, and a real safety issue if they fail.

If removal of the fork doesn't work out, consider making a castor that mounts with a skewer in place of the front wheel. This would be off the road most of the time, unless it drags on a speed bump or like such.

The castor pivot axis needs to be very near vertical, so this isn't trivial either, but I'd feel a lot better about it than trying to make a safe but removable fork.

Thanks for the input. Once the bike arrives I can look at what my options are. I'm hoping its a threadless headset. The forks and handlebars can be removed.

... and thanks to everyone for their suggestions. I ordered the Black SKS Fenders P35's and will work on the "shield" solution to attach to the front of the trike boom.
