Therefore the GTC Compact Touring Trike has been specially designed for the smaller person, using 16" wheels all round instead of the regular 20" wheels. These wheels are the same wheels as used on the both the GLR Race Trike and the GTX Sports Trike.

要するに、身体の小さな人向けのトライクもGreenspeedで作ってるよ〜♪ということです。もちろんLOGO TRIKEもいいけどね。
