Lake Park build: phone holder + mirrors included, and select builds add a tail bag. Assembled, tuned and safety-checked by Tony.
The Thunder Pro ST takes Jasion's big fat-tire Thunder Pro and lowers the top tube, so getting on and off is a step, not a leg swing. It is still a serious bike: 26 x 4 inch puncture-resistant tires, a hydraulic front fork with lockout plus a rear soft-tail, 180mm hydraulic disc brakes and a rear rack rated for real cargo. Tony builds and safety-checks every one before it leaves the shop.
Reserve online with no payment now and we will call to confirm the color, timing and pickup. We are not selling e-bikes for online checkout.

Yes. ST stands for step-through: the top tube is lowered so you can step through the frame to get on, which is easier on knees and hips than swinging a leg over.
