When you hear the motor bogging down, pedal harder and release the throttle to the point the motor sounds more normal. Perfect advice, melted the nylon gears on a geared hub motor like yours pushing it to 1000w (48v 20a) when I let it bog down going up a steep hill. It is less likely to happen to y...

Welcome to the forum mastermind1234321, DIY setup depends on your mechanical skill. Can you repair a bicycle flat tire? What is your budget? how far do you need to go? Otherwise a factory built ebike will be a reliable workhorse that will probably meet most of your needs and last you years. I am int...

You want help we need link to said motor kit. Oh and by the way it helps us help you if you follow wenewell advice.

I would get a voltmeter as wesnewell recommends. I have fixed problem battery packs as you described. The way i fixed them was to open up the pack. With a voltmeter probe between cell 1 and 2 then between 2 and 3 then 3 and 4 etc. etc and check each voltage reading. You will see which cell is weak a...

Correct me if i am wrong but does your dropouts have a space of 150mm? From the picture it looked that way. If it is true you might have lucked out and can replace that geared motor with a powerful 3000w motor. You can run it at 48v and a cheap generic Chinese 9FET controller, if possible trim it do...

Totally agree with d8veh, I have built all three of the ebikes hub motors that you are considering. For a light weight racer the Q100 is the BOMB. The SWXH is a nice motor too. The thing you have to be aware of with the Bafang SWXH is that it is noisier and heavier. The 6T wind I have not worked wit...

I've seen a Prodeco Outlaw in person that was chained outside a store and gave it a look over. If you're going to feed the motor more power (especially amps) in an attempt to reach 40mph, the phase wires will need to be upgraded (it has the dinky 6 pin "XLR" type connectors) and the torqu...

It is a matter of personal endurance. I agree with the MadRhino, though it is not that hard to ride in winter conditions with the right gear. Spike tires are the first priority. Poagies are also very helpful in keeping your hands warm because that is the part that gets the coldest when riding in wi...

I am very interested in this. I believe that the MXUS 3000w hubmotor has potential. What has me on the fence is the skinny phase wires. I have a 1000w MXUS now and has the same size wire. The wires already get very hot when i run an infineon at 2000w. Can you imagine the new motor at 3-4000w? This h...

I agree, I have clamping dropouts on my front forks of my heavy duti cruiser and having the pinch bolts on top aesthetically look better. Had them on the bottom and it looked weird. Easier to loosen the bolt before removing the wheel as well. wouldn't it be more preferable to have the rear dropout h...

Exactly! You can get good service, you just need to know exactly what you want, then you need to know what to expect. search bmsbattery on this forum and you will see alot of success and alot of failure. I personally have had alot of success like d8veh. My orders with them total around 15. If you do...

Sorry about your BMSB experience, It really sucks. Be patient, hopefully your stuff will be here before the winter kicks in. If you paid with paypal you can always file a claim. You can even threaten bmsb that you will file a paypal claim. That usually gets them to ship faster. Getting what I paid f...

You get what you pay for. Next time go with http://www.ebikes.ca/.

good catch neptronix, totally missed that. Won't fit in a standard mountain bike without modifications.

Kepler, code 12 sounds interesting. Is there a sure fire way to get a code 12 from BMSbattery? Or where would you get one? I have a Bafang BPM code 11 by ordering the Bafang BPM 36v 393rpm.

I had it set to 100%, I think this is why my controller is broken. I think this may be when you first press the throttle, it is the minimum throttle level that is applied. if setting it to 1% it shuould give a good range of throttle, whereas 100% turns the throttle into an on/off switch. Who did yo...

Shipping batteries to sweden from china is expensive. First you pay and extra shipping fee for hazardous material, then the tullverket spanks you for another 25%. The solution is you can get a decent Lithium Ion 36v 10ah battery from the swedish equivalent to radio shack for a reasonable price. http...

I have not ordered yet, still thinking of where to get it. Everything goes for about $670 at BMSB, plus shipping $240 and maybe they will ask for more have I heard so total over $910. Not that cheap anymore... So if anyone has a similair package for better price/anotfher vendor please tell me :D Yo...

If you like Regen don't let people sway you otherwise. 2 primary advantages are: 1. Safety- Especially going down hills it allows your mechanical brakes to be fresh and cool and ready for emergency stops at all times. This is even more important with an ebike, because the added mass of the electrica...

pendragon8000, I have read your whole thread, nice work turned out great. I am interested in converting a Scott Spark 35 full suspension bike, can you show us the torque arm you used to secured the hub motor? Has the Regenerative braking caused any problems?
Thanks Racer_X

A 250w motor and 9aH bottle battery will not give you enough power or torque for your weight. a Weight of about 100kg (220lbs) would be about the max. Do yourself a favour and get a 500W geared motor and minimum of 20A controller. The 201 rpm 500w rear BPM kit from BMSBattery will be perfect for yo...

No worries sfynzy, but remember this is my opinion. Wait until other people chime in. They should come up with new insight, another ebike source OR add something i might have missed. Can you post a link to the hub motor you are interested in? Extra throttle, e-brakes, motor gears, freewheel (if rear...

I believe you since this move will be a shift from a previous position I was in which was riding an escooter (350w direct drive). But since it will be my first attempt at building it (as easy as it looks) I'd like to start small, and I believe I can sell it off once I want to move on. I intend on c...

I weigh around 300lbs +- and am on a very tight budget so I went to alibaba to look for a kit that is affordable for me. I found a kit, 250w geared hub motor and comes with a 36v 9ah bottle battery. For long life and your size you need either a 500w or more Geared motor OR a 500w or more Direct Dri...

Yes but we are talking about a 50 cent item. Thanks for the capacitors information, did not know that. For me the big trouble I had was the wearing of the contacts due to constant spark upon connection, though i agree it is only a 50 cent item. That 50 cent item can cost you when you least expect.
