The recent popularity of double treadle spinning wheels combined with Louet’s durable design and leading edge technology lead us to the S51 DT. It treadles smoothly in a similar bicycle fashion at the S75. Accessories available for the S51 include: skeinwinder, distaff, a four bobbin lazy kate, high speed bobbin, fatcore bobbin, flyers, and various spare parts. Technically all Louet models are the same. Each S51 wheel has a single belt bobbin drive with an adjustable flyer brake to regulate the tension. The flexible belts are made of polyurethane and never have to be adjusted. All wheels are packed and shipped partially assembled in a flat box. The required assembly consists quite simply of tightening two nuts for which tools and instructions are provided. The shipping weight is 17-18 lbs.
