Thank you for purchasing a Downtube bicycle! We hope you will years of enjoyable use from your new bicycle. Please read the entire manual before operating the bicycle.
Your Downtube bicycle is 100% assembled at the factory. You should take this bicycle to a bike shop to get it checked and tuned by a bicycle professional. The shop will be able to find problems that may make your bike unsafe. Please give the below check list to your mechanic and make sure they go through everything.
1. Lubing the Chain with White Lightning is highly recommended. Please note the chain must be completely clean before applying White Lightning.
2. Check the frame quick release for play every ride. Tighten the quick release as necessary.
3. Check the headset and stem to make sure it is not loose weekly.
4. Check the brake shoes for wear weekly, replace as necessary. We recommend Kool Stop pads as replacements.
5. Front & rear hub, headset, and bottom bracket bearings should be repacked with grease once a year
Be careful when braking under wet, rainy, muddy, snowy or icy conditions. Wet rims require more distance to stop. Never lubricate the side wall of the rims or brake shoes this will make the brake ineffective.
Check tire pressure weekly. Adjust if necessary with a standard schrader pump between 40-60psi.
Spin each wheel slowly and look for cuts in the tread and sidewall. Replace damaged tires before riding. Spin each wheel and check for the brake clearance and side-to-side wobble. If a wheel wobbles or hits the brake pads, take it to a qualified bike shop to have the wheel trued.
Use Allen wrench to change the angle of the handlebar by loosening its binder bolt, rotating the bar or extension to the desired angle, re-entering it and re tightening the binder bolt enough so that the bars or extension can’t move in relation to each other and the stem.
If the stem is not properly aligned with the front wheel, it will need to be adjusted. Loosen the stem bolt just above the headtube. Place the front wheel between your legs and twist the handlebar/stem assembly to align the handlebars in relation to the stem. Then re tighten the stem bolt.
Warning: Failing to properly tighten the stem binder bolt or the handlebar binder bolt, you may compromise steering action, which could cause you to lose control and fall.
WARNING: Do not over tighten the stem bolt or other clamping devices; there is a danger of damaging the stem and the fork and risk of injury to the rider.
Want help picking a comfortable saddle? email yanL@downtube.com with your specific needs and he will give a recommendation. Correct saddle adjustment is an important factor in getting the best performance and comfort from your bicycle.
Your leg length determines the correct saddle height. To check for correct saddle height go to our instructions page at https://www.downtube.com/Proper-Bicycle-Saddle-Height-Adjustment-s/130.htm
To adjust the saddle height, loosen the seat post quick release and move the seat post up or down as required. Re tighten the seat post by locking the seat post with quick release. Make sure that it is tightened enough and you cannot twist the saddle easily out of alignment.
WARNING: The seat post must NOT project from the frame beyond its minimum insertion or maximum extension marks.
To find the most comfortable position, please view https://www.downtube.com /Bicycle-Saddle-For-Aft-Adjustment-s/131.htm
WARNING: After any saddle adjustment, be sure to tighten the saddle adjusting mechanism properly before riding.
WARNING: Folding bikes ride lower to the ground than normal bikes. Do not turn sharply or hold the bike at an angle while riding. This may cause the pedals to hit the ground and the rider may loose control and crash.
Both pedals are foldable. Push the pedal inward to the crank. Then fold it downward. To unfold, simply lift it up perpendicular to the crank.
2. Fold downward
Reflectors are important safety devices that are designed as an integral part of your bicycle. Do not remove them on any circumstance. Keep clean and replace them immediately if found damage.
Detailed instructions on adjusting brakes can be viewed at https://www.downtube.com/Bicycle-Brake-Adjustment-Instructions-s/120.htm
Brakes on your bike are adjusted when you purchase the bike. They allow you to adequately slow down and stop the bike when the brake lever is squeezed. Periodically checking and adjusting the brakes is strongly recommended. Braking cables can be tightened/loosed by rotating the barrel adjuster nut on the brake levers (clockwise/counter clockwise). The V-brakes on this bike have quick release mechanism and allow the brake shoes to clear the tire when a wheel is removed or reinstalled. When the brake quick release is in the open position, the brake will not operate. Make sure you understand the way the brake quick release works on your bike. Consult local bike shop or bicycle technician for detail whenever is needed.
WARNING: The shorter the brake lever reaches, the more critical it is to have correctly adjusted brakes, so that full braking power can be applied within available brake lever travel. Brake lever travel insufficient to apply full braking power can result in loss of control.
Check that the brake quick release is close and the straddle cable is securely engaged. Squeeze the brake levers. Confirm that the brake shoes are contacting the wheel rim within an inch of brake lever movement. You must be able to apply full braking force at the levers without having them touch the handlebar grips. Otherwise, your brakes need adjustment. Do not ride until the brakes are properly adjusted.

In order to allow the folding bike to stand upon the ground properly after folding, perform the following steps:
STEP 1: Loosen the seat post quick release and push the saddle with seat post down to the bottom. Then slightly tighten the quick release again.
STEP 2: unlock the quick release of the handlebar stem and fold the handle bar stem downward to the right hand side of the bike.
STEP 3: Set the kickstand to the ready for riding position (kick it up horizontally).
STEP 4: unlock the quick release of the frame and fold the front part of the frame to left.
STEP 5: fold the right and left pedals.
The steps are completed.
