hi my name is Mike Harding I'm a product engineer for the assault air bike this is the bike that I have at home uh today I'm going to go over some maintenance tips some routine maintenance uh that'll help keep your guys' bikes running uh smoothly and safely here's some tools and cleaners that you're going to need the torque wrench and the crank pul or from Park Tool are available at your local bike shop and here's a table showing the schedule and the routine maintenance steps that are going to be [Music] performed the first thing that you want to do make sure you do for the bike is to clean it well uh when people are on these they're kind you guys are doing some hard intervals on them and you guys are sweating really hard sweat comes down on the bike and sits on the bike it's going to end up uh causing some corrosion so pretty much every day you want to make sure that the bikes get wiped down the main areas that you guys want to look at for cleaning the bike is the places where sweat is going to pull and it's basically right below the user and then anywhere down on the bottom of the frame so the cleaner that we like to recommend is the diluted version of The Cleaner Simple Green another real common area for sweat to uh find a sort of a hiding place is on the seat tube and then wipe down on the inside here so two main areas on maintenance of the bike one is keeping it clean and keeping it clear of human sweat the other thing is that you guys are using the bikes in a real high intensity uh kind of a uh interval type uh workout and that puts a lot of stress on the bike frame moving pars and drivetrain so the second part of the maintenance is that we want to go through the bike and make sure that any of the linkage points or the Fasteners are all staying nice and snug once some of the parts are allowed to get loose uh specifically the cranks and pedals if you allow those parts to get loose then they're going to quickly wear out and those parts will have to be replaced rather than just tighten okay so checking the bike for just general operation I just called the the pedal toest to just sit on the bike and pedal away you want to be aware of basically basically that the drivetrain is operating smoothly and fairly quietly obviously the bike is on the loud side because of the the fan that's pumping the air but you want to be aware for any uh unnatural noises any clunking or squeaking or squealing or something that might indicate something's wrong so one other thing you want to look at while you're pedaling the bike is just to check to see that you're getting a steady RPM signal on the console if you are not seeing uh signal then you're going to want to look to make sure that the speed sensor is located so that is coming close to the magnet that is mounted on the fan okay so this one sounds pretty good the other thing you want to do on the bike is sort of push back and forth on the handlebars and you might feel just a little bit of a looseness and that's normal but if you feel a lot of looseness in the handlebars then there's something uh usually in the dri Trin that's going to be a little bit loose and needs to be tightened you can also do that by moving the crank arms back and forth a little bit same thing you shouldn't really feel any looseness there so now if if you do feel any looseness uh in the dri train the thing that you're going to want to check is the is the chain tension first off so let's go down and take a look at that checking the chain tension is not necessary to remove the chain guard but I'm just going to do it uh so that everybody can see a little bit more clearly one note of caution also is that this is a direct drive system so if you get your fingers in this area or this area uh they can get pulled in uh which you don't want to happen obviously when you're working on the bikes and you have your fingers down near the chain uh make sure that nobody else comes up to start pushing on the handle bars or something the way tension the chain on this bike is first you're going to set the tension on the first stage here okay and then when this is set then you're going to set tension on the second stage up here okay we're taking a look at the chain tension now if the chain is coming up by more than one thickness of the chain basically then it's a little bit this is a little bit on the loose side so to uh tension the chain first you want to loosen uh this 15 mm okay loosen this up you loosen this to allow the chain to be tensioned the 10 mm nut here is what's actually going to control the tension in the chain so to tension the chain we're going to want to tighten this one and you can put your finger here and you can feel it getting Tighter and that's just about right that's just about how you want it just a little bit of mov if you do over tension the chain chain uh then it's going to put more stress into the chain Chain's going to wear out and so will the the chain wheels so once you have uh once you have the chain at the proper tension now we're going to tighten up the 15 mm nut now we're going to take a look at the second stage chain okay so moving this one up and down the amount that the second stage is going to move uh the Chain's going to move is is quite a bit more than the first stage because there's a longer span this is just a little bit on just a little bit on the loose side okay so we're going to tighten that up I'm going to start with the 15 mm wrench here loosen this main nut first the 10 mm bolt here is what's going to actually put tension in the chain so you can just put your 10 mm wrench in there and I'm just going to move it about two turns and then check it just a little bit more okay that's that's basically the tension that you want so now we want to go ahead and tighten up the 15 mm bolt want to really make sure that we get this 15 mm bolt snug if it's not uh quite tight then that's going to allow the chain to move back a little bit and loosen up a little bit okay now we're going to take a look at uh how to lubricate the chain here are some chain lubricants that we recommend they're available at your local bike shop uh the best is to uh use can that has a a straw on it and uh what you're going to do is stick the straw down through the fan cage like that and then just give it a little bit while you're pedaling that should be enough then uh once you have some lubricant on the Chain you want to go ahe and keep on pedaling it for a little bit that'll help the lubricant work its way into the inner parts of the chain where you need it okay after we lubricate the chain on the second stage we're going to go back and lubricate the chain on the first stage all right one of the real critical areas on this bike is to make sure that the the crank and the bell crank bolts stay tight uh if these parts are allowed to loosen up at all they'll quickly wear out and they need to be be replaced on the crank bolt and the bell crank bolt want to use Loctite 262 for the tightening torque on the crank bolt and the bell crank bolt we want to tighten those to a reading of 50 Newton M you can get a torque wrench uh from your local bike shop generally the pedals will stay pretty tight um but if you do start to feel uh when you do the pedal test if feel a little bit of clunking that might be because the pedal is coming loose the one little trick on this bike is that the pedals the right hand side is a regular right hand thread and where the left hand side is a left hand thread so easy guideline to remember uh that for tightening the pedals if you had the wrench on the pedal okay 15 mm wrench okay to tighten the pedal you're always going to move the wrench toward the front of the frame to loosen the pedal you're going to move the wrench toward the back of the frame and the pedals don't need to be overly tightened okay another super important part on this bike to make sure it stays tight it does take a lot of abuse is this nut the main nut that's holding the handle bar onto the frame okay it was part of the initial installation that you guys did when you put the bike together it's 22 mm nut so you can use an adjustable wrench you want to try to keep these both pretty pretty darn not good all right now we're going to look at the uh the connection between the linkage arm and The Handlebar and there is uh Ball Bearing in this area but we want to use a 6 mm allen wrench and a 13 mm uh wrench for the nut that's on the back side okay so again we're just checking to make sure that this is tight okay we're getting down to the wire here uh just the last couple things while you're down here just double check these uh Fasteners holding the front and rear stabilizers that those are still snug and tight and then these two uh Fasteners up here that hold on the uh console Mast okay now we're going to check the seat adjustment uh basically we're going to look at this uh the 13 mm bolt that secures the seat if that uh just want to make sure that that connection is tight enough so that the seat won't be able to rock from uh side to side thanks thanks very much for taking the time to watch this video and uh just wanted to reiterate that the bike was designed to be very durable and uh take all the abuse that you crossfitters are dishing out uh but uh routine maintenance really is a must uh the bike does need to be maintained uh to ensure smooth and safe [Music] operation
