benny,
Will Challenge your observations on electric truck percentages for North America, primarily the US market. Historically, Class I electrics (sit down & stand-up counter balanced riders) account for about 24-26% of annual sales, Class II narrow aisle & order selectors about 12-14% and Class III battery powered walkie (low lifts & stackers), tow tractors 28-30%. The balance is engine powered cushion and pneumatic with cushion tire units being about 19-20% and pneumatics 17-19% Electric product sales will have higher percentages than ICE sales during slow economic times as the prime users are in the food & food distribution industries.
Canadian sales have a different sales mix with higher sales in pneumatics than cushion, ruffly the market size in Canada is about 10% of the US and sales in Mexico are very heavy in pneumatics and electrics of all types are about 10% of the total.
In Europe you will find a very small numbers for cushion (press-on solids) sales than in North America (some in Germany & a smattering or two in Great Britain). About 94 to 95% of cushion units are sold in N. America and a few escape to Australia.
