Tern Bike Size Chart

1. 01

   One frame, one published range per model

   Tern lists 10 models on this page. The ranges start at 142 cm on the Verge and Link and stop at 205 cm on the HSD S9i Sport. Every model is one frame with a telescopic seatpost, not a set of frame sizes. Two models can share a range and still produce a different fit, because the frame length and bar position change.

2. 02

   The trim changes the range

   Read the listing for the trim you will buy. Tern lists the GSD P10 for 150–200 cm and the GSD S10 for 153–200 cm. Tern lists the HSD P5i for 150–200 cm and the HSD S9i Sport for 153–205 cm. The frame is the same. The seatpost and stem differ. A 151 cm rider fits the GSD P10 and sits outside the GSD S10. Order the trim whose spec sheet lists your height.

3. 03

   The lowest range starts at 142 cm

   Two models start at 142 cm. The Verge and the Link cover 142–190 cm. The Eclipse, the Node, and the Short Haul start at 147–148 cm. The cargo bikes start higher: the GSD and the HSD P5i at 150 cm, and the HSD S9i Sport at 153 cm. A 145 cm rider fits a Verge or a Link and sits outside the GSD range.

4. 04

   The highest range stops at 205 cm

   Of the 10 models, 7 finish at 195 cm or higher. Verge covers 142–190 cm, Link covers 142–190 cm, Short Haul covers 147–190 cm, BYB covers 147–195 cm, Eclipse covers 148–195 cm, Node covers 148–195 cm, GSD P10 covers 150–200 cm, HSD P5i covers 150–200 cm, GSD S10 covers 153–200 cm, HSD S9i Sport covers 153–205 cm. A 198 cm rider fits the GSD P10, the HSD P5i, the GSD S10, and the HSD S9i Sport. The other 6 models stop below 198 cm. Check the maximum saddle height and the seatpost extension mark on the spec sheet for the trim you will buy.

5. 05

   The rider height range does not cover cargo

   A Tern rider shares the frame with a passenger and a load. The rider height range says nothing about the gross vehicle weight. Read the maximum gross vehicle weight on the model page. Tern lists it for every bike. Match the rider, the passenger, and the cargo against that number before you buy. A bike that fits the rider can still fail the load limit.

6. 06

   Wheel sizes differ across the folding range

   Tern builds the folding range on four wheel sizes. The BYB and the Link use a 20 inch wheel, the Verge uses 451, the Node uses 24 inch, and the Eclipse uses 26 inch. The wheel changes the rollover and the folded package. Read the wheel size with the height range. A 26 inch Eclipse rolls over rough pavement with less effort. A 20 inch BYB folds smaller.

7. 07

   Add a passenger after the frame fits

   A cargo Tern carries one or two children. The rider height range and the passenger capacity are different numbers. Check the maximum gross vehicle weight, the rack limit, and the child seat compatibility on the model page. Set the saddle and bar height with the passenger aboard, because a loaded bike sits lower at the rear.

8. 08

   Set the saddle and bar height after delivery

   The Andros stem and the Speedlifter stem adjust without tools. Set saddle height first, then bar height, then bar rotation. Sit on the bike with the ball of the foot on the pedal at the bottom of the stroke. The knee keeps a slight bend. Write down the seatpost number so a second rider can return to your position. Tern prints a scale on the seatpost for that.
