ok that helps. sounds pretty straightforward if the kit fits the bike you are good to go. Also, dont worry about ebike rated chain or casettes... its still cheaper to buy normal KMC bike chains and cassettes... You replace cassette after going through about 2-3 chains as chains wear faster than your cassette. Again its cheaper to go with regular chain/cassette and replace those more often, no downsides to it. I got over 1k miles on my ebike, still on first chain, no problem. As long as you understand how to ride smooth and stay in the right gear theres little concern for excess drivetrain wear. the gear shift sensor helps a lot with smooth shifting on ebike.
1 What are your use case and range requirements: Use commute to work 5miles each way on asphalt flat road it has to bridges 15 to 20 deg incline 300ft to crest.
I have a BAFANG BBS02B 48V/36V 500W MOTOR W/ battery 48v 20ah this should be more than enough for my requirement.
I have brake sensors and gear shift sensors
Everything fits well on the bike
2: What is your Bike Frame Model : 8 speed Raleigh hybrid full disc brakes 26" MTB wheels hardtail Bottom BB perfect for the bafang motor no chaing interference . I will be using cable pull hydraulic brakes not full Hydraulic front wheel has 180mm discs 160 in rear.
Bike is to be used strictly for commuting to work only no crazy offroad stuff
I am at the point now of carefully choosing my drive train
Chainring is 44t I was thinkig of using 11-28t cassette I think would be good enough for my needs my legal assisted speed cannot go more that 30kmh
Reading a few blogs and watching few videos chain and cassette wareout faster on
e-bikes.
So just want to choose a good cassete and chain that can handle the rigors of an e-bike vs regular bike and have it last longer . With the communities experience what is a good Cassete and chain suggestions for 8 speed e-bike

Factors and Questions to consider for Ebike conversion:
Please answer the relevant questions when asking for help on a new build in the forum.
1. What are your use case and range requirements?
-Preferred terrain - hill climbing or flat, mostly smooth hard ground or sand / snow / mud (latter ideally suited for fat tires)
-How much range do you want on a charge? - This determines what motor power and battery capacity youll want.
Multiply Volts x AmpHrs = WattHours ie my 52v 20Ah battery yields 1040 WattHours, or about 30-50 miles of range on a charge depending on how high PAS levels or throttle I use
2. What is your Bike Frame Model - Does it fit you properly? Is it full suspension or hard-tail (latter preferable for ebike due to ease of conversion). Is it quality enough to be worthy of an ebike conversion? (avoid putting high end ebike kit on a low end frame). Make sure you double check the battery dimensions that it will fit on your bike frame properly...(full susp frames often have a hard time fitting). Do you need folding, or other features? A hardtail with good front suspension fork and a suspension seatpost will perform well in terms of comfort vs a full suspension bike, and is easier for ebike conversions. Keep in mind fat tires ebikes are more suited for sand, snow, mud, roadways, while narrow tires are better in mountains, trails, forests, for agility, and need better suspension due to less tire cushioning.
3. Do you need more torque for climbing steep hills or more top end speed for flatter terrain? This relates to your ideal cassette / chainrings / drivetrain setup. Ideally you want at least 7-11 speeds/gears on rear cassette for ebike conversion, 10 speed is a great choice. Mine for example is 10 speed 11-36T cassette. Shimano Deore / SLX derailleur. Front chainrings/derailleur will be replaced with one ebike chainring up front. Find the best chainring for your use case. 42T using a BBSHD tends to the be sweet spot for me for steep hills / climbing - just enough to not be too torquey, popping wheelies too easily even while climbing steep inclines its a bit uncomfortable! I reach 50-60 kph on flats with just the motor, plenty fast. If you dont have too much steep terrain, more gradual hills and flatter terrain, a 46T stock ring may be the sweet spot for you, or up to 52T for more speed (higher Tooth count = lower torque and higher top end speed, lower tooth count = higher low end torque for climbing, lower top speed). Lekkie blingrings perform better at gripping the chain if you have chain jumping issues. Front chainring just want a slight gap off the chainstay, 1/8 to 1/4 inch, use motor spacers if needed.
3. Whats your budget? - Again ideally dont put a 1k+ ebike kit on a cheap 400$ frame…youll likely end up with a subpar ebike. Why bother on a walmart bike with no suspension youre butt will be sore! Better to match a budget bike with a similar value ebike kit. You can move the kit to a new bike also later. High end frames are more suited for a better ebike kit.
4. Do you have all the necessary tools, parts, bike accessories for the conversion? Are you sure youve done the research on your desired bike, made sure it fits you and is compatible with the ebike kit you want to install? This is to ensure no buyers remorse. Have you watched the conversion install video guides for bafang kits, and how to carefully program the controller post install, so you are fully ready to convert the bike? Its all pretty straightforward with a lot of resources out there though it may seem intimidating at first - actually finding my ideal MTB frame and converting it was a ton easier than sifting through hundreds of pre made ebike models…custom ebikes are the way to go!… You can see my completed build with my part list and links to controller programming guides are there. Good luck, feel free to ask for help.
My commute would be 5mile asphalt two medium size hills.
Also trying to determine type of cassette material to use for an ebike application I understand with ebikes the cassete and chain take a lot of beating does not last very long so I am looking for proper chain and cassete for ebike suggestions like brands models
depends... what is your terrain use case, mountain/hilly or flat? generally most mt bikes will be 8-11 speed cassette, 11 tooth to 36t (in my case). Im in mountain terrain so I use a 42t. it almost matches the rear gear in teeth. If i dropped to a 36t front chainring, my torque and climbing power would go way up. for my setup 42t is perfect for all terrain use, climbing and flat. hope that helps
Ok thank you that takes bit off mind greatly appreciate your thoughts.
Like you said just have to learn proper gear shifting
