Bulls Bike Size Chart: Read Reach and Standover Before Choosing
A Bulls bike size chart is useful only when its numbers belong to the model under consideration. The Copperhead EVO 2 750 Wave table presents an unusual distinction: listed standover stays at 490 mm across four sizes while reach and stack change. Choosing the smallest frame solely to reduce that chart entry therefore misses what the table says.
Bulls bike size chart: the Wave columns
In the manufacturer's order, the frame labels are 41, 44, 48 and 54 cm. Reach is 428, 433, 441 and 461 mm. Stack is 675, 675, 675 and 694 mm. Keep each horizontal measurement beside its corresponding vertical measurement rather than comparing a single headline size.
From 41 to 44, the listed reach increases by 5 mm while stack remains unchanged. Moving from 44 to 48 adds 8 mm of reach, again without a stack increase. The final step, from 48 to 54, adds 20 mm of reach and 19 mm of stack. These are differences calculated from the chart, not measurements taken from a bicycle.
Separate access from handlebar position
All four standover entries read 490 mm. That common figure does not mean identical frames or identical saddle positions. It also is not the height of a fitted saddle. A rider comparing the three smaller options faces changing reach even though the two other reference rows remain constant.
The Copperhead EVO 2 750 Wave listing identifies its colour as Light Gray/Black Matt/Gold. Keep the specific Wave listing beside the chart, so these dimensions are not applied to an AM Carbon or an older diamond-frame Copperhead.
Use the chart to ask a narrower question
The manufacturer's separate height-and-inseam helper explicitly calls its recommendations a reference. It cannot settle whether the controls are comfortably reachable, whether mounting works for you, or how the complete bicycle feels when stopped. Bring those specific questions to a fitting or demonstration rather than expecting the size label to answer everything.
Record measurements from a familiar bicycle if available, and keep the measurement names clear. Reach, top-tube length and stem length are different entries. The historical photograph supplies no current Wave dimensions and is not a scale drawing. Browse the Bulls topic and company guide when comparing the wider range.
FAQ
Which Wave has the lowest listed standover?
The table gives the same 490 mm figure for all four sizes.
Does moving from 44 to 48 raise listed stack?
No. Both entries are 675 mm, while reach increases by 8 mm.
Can the old photograph establish a Wave size?
No. Confirm the actual model and frame label before applying this chart.
