2 wheel drive conversions were the origins of Trykit Conversions in 2002. Many tricycles have now been converted from one wheel drive to the Trykit cassette based two wheel drive setup. There are also many Longstaff tricycles with the old Sachs double freehub that have long since worn out and, unable to obtain new sprockets have now been converted. Longstaff single wheel drive trikes are converted too. The Trykit Cassette 2 wheel drive was the first cassette system to be produced for trikes back in 2002. It was designed and manufactured completely in house by Geoff Booker. The cassette body will accept any Shimano or SRAM cassettes up to 11 speeds without any spacers being added or removed. Trikes that are convertible are, Higgins, Rogers and Longstaff machines and any other makes that incorporate their axles. Higgins and Rogers machines require new drive shafts to be made, and the cup and cone bearings replaced with deep groove sealed bearings. The shafts can have either standard Higgins / Rogers hub ends, Trykit ends or Longstaff ends. All hubs are kept in stock with a choice of spoke drilling to suit requirements. To go with the extra sprockets and later indexed gear systems, Trykit also manufacture a redesigned gear hanger that is designed for indexed gears, and will also improve gear changes on non index systems.2 WHEEL DRIVE CONVERSION PRICESAll Longstaff two wheel drive, single and tandem trikes converted to Trykit two wheel drive with modified drive shafts £360.00 Or with four new drive shaft bearings included £400.00Longstaff one wheel drive to two wheel drive conversions £390.00 Rogers and Higgins two wheel drive conversions with new drive shafts, and deep groove ball bearings fitted to modified bearing cups. £420.00 Rogers or Higgins Tandem trikes converted to two wheel drive.
