Bike build for friend...

I have a friend at work who expressed interest in starting to ride for his health. He asked if I could assemble him a beach cruiser style bike. My friend is about 5’9” and 425lbs. I am thinking of good solid double wall rims like Rhyno-Lite XL’s and he doesn’t want a coaster brake so Sturmey Archer drums front and rear. Would this rim be strong enough for him built with quality 14g spokes? I am open to any other suggestions!

Since this is a single speed, spoke problems are less of an issue than for multi-geared bikes. Rhino-Lite will be just fine but so would just about any rim of good quality.

However, any wheel problems that will develop given the weights involved will be spoke problems, not rim problems. Concentrate on the proper part of the problem which are going to be the spokes. Build the wheels with DT Alpine III or Sapim Force or Wheelsmith DH13 or Pillar PSR. All of them have thicker, stronger heads which will stand up far better to the demands placed on these wheels for longer than a 14 straight gauge spoke will.

The Sapim "Strong" is a single-butted 13/14 gauge and is recommended for heavy loads. I just built a wheel with them and they were a breeze to work with and fill the spoke holes in the hub nicely.

The Rhynos are bombproof rims. At 425 lbs, this is a perfect scenario for cyccommute’s recommendation for triple butted spokes. Seek out the talent of a quality wheelsmith and you’ll have little to worry about.
