Strangely; we've noticed that our Blue State competitors say nothing about guaranteeing their frames against any tank leaks so buyers beware!   

We can take volume export orders for frames shipped direct from the China Frame factory to qualifying distributors in USA, Europe, Australia, and South America and Canada.  MOQ is 200 frames.   We inspect what you expect. 

Please know that Gru-Bee was the first to design and provide built in gas tank bicycle frames over 13 years ago.   Accept no substitute;   All others just copy.   Most copy frames have 2.4 to 2.7L capacity gas tanks but now larger tank frames are being advertised.  Remember, Paint will not permanently seal a tank leak for very long.   

Tank leak testing must be done before painting.    

This is our latest design frame with a bigger gas tank that holds approx. 3.5 to 3.7 Liters.    Seat and chain stays now are made of heavier ga. alum. than first design.   Gussets supported pedestal mount.   Disc brake caliper attach on left rear.   Can also use V caliper brakes if desired. 

    Our Frames now are made more heavy duty than early production;   Gusset reinforced pedestal mount.  No more broken or cracked pedestals front engine mounts.   

    Thicker metal now in seat and chain stays. 

    Bigger capacity gas tank.   100% Pressure tested for leaks.

    Small bottom hole frame avoids the need for using a WP-CK big hole to small hole conversion kit to accommodate a 3 pcs pedal crank.  

    Select PC paint colors or unpainted in raw aluminum finish. 

    Packed in double cardboard boxes for secure shipping.
