Tandem owns bike brands Falcon, Dawes, Claud Butler, Shogun, British Eagle and Optima. Character-licensed child bike specialist MV Sport Group is also a part of Tandem.
Chairman Graham Waldron said:
"Our bicycle business made a good start in the first quarter of the current year with increased turnover and margin and reduced overheads. Demand weakened in the second quarter, resulting in a lower turnover for the six months compared to last year. The level of improved margins and reduced overheads was maintained resulting in increased profitability for the six months over last year."
MV Sports Group, once one of the engines for profit at Tandem, suffered last year.
"Turnover [at Mv} is down on last year due to the closure of a significant catalogue shop customer, increased competition against some of our longer established licences and a general malaise in the retail sector. Although the margins were maintained, our lower overheads failed to compensate for the reduced turnover. Profitability was down on the excellent performance for the first half of last year.
Tandem PLC also owns the Ben Sayers golf brand and the Pot Black snooker business.
