It's 12kw and lasts an hour on a 1.5kwh battery. That's great engineering that is.

If it was two lead acid they would be 13.8v full charge each so about 27.6 volt expected. If your battery is only 26 volts it's a bit low. what is the current rating of both battery and bike, If it's too low voltage sag would stop the function straight away. Have you any details?

I know that they are an old design but they are developing. The seventies began the Renaissance with human powered vehicles. The are the future just ask Sir Clive Sinclare

I wouldn't bother with that kit. You have front disk brakes. DD motors struggle with torque(grunt). If it has any it's not good with front forks unless they are steel. The speed will make you stand out and risk your driving licence. If it is 1kw it would flatten even a 17ah battery in half an...

NNNOOOooooo, Don't touch the self destruct button..

I most strongly disagree. Cutting edge in cycling is recumbents. Comfortable and energy efficient. That's the cutting edge. Electric motors are so old from around 1920's I think. Humbug mutter mutter.

no power in first gear it should be easy to spin the pedals. It should only be hard at speed or hills. You shouldn't need to turn the motor off, leave it in Eco and the assist will fade at 15 mph so you reach a balance of a little assist to effort.

Nice pad you have their man.

Welcome, What bikes are you looking at?

Trex has given you the general Chinese bike advice, most bikes have chinese parts so don't worry about that. I would only disagree about the battery, bigger is better especially if you need health assistance. My advice is to test ride as many as you can. The better handling the bike without...

At those prices a Rohloff 14speed ? It should last a life time and chains are cheap for it.

I know but if he needs +,- is then it is stretching the safety issue

Well it probably cheaper to get an eBay bargin with suspension, disks and hub gears . Then it's a plug and play.

He isnt going to get 5400 amps the likely is 5.4a *25c= 125+ amps more that the motor can take. Usually 20 amps is max and then the battery will be lucky to last 15 mins. And that is near 2kw. Smoking .. It could all end up smoking !

Welcome , Convert the Galaxy. A good frame and wheels will run well with a conversion. Mid or hub, try to get a torque sensor as that will feel natural to you just young again;)

If you are struggling with these diagrams then I am worried that the balancing and care needed for Lipo batteries will also be hard for you. As the risk is burning your house down.... Please reconsider what you are doing. You need to keep the cells balanced, with a balancing charger. Monitor the...

Toughen up the chain line by going single speed. Chain that is then fit a rear hub gear. Alfine 8spd is tough and good range. Rohloff is the brankrupting biz. Then what ever mid drive kit suits the electrics are fairly basic the heavy twin core together, multi pin plug too display,two bake...

Photos or it didn't happen..... Joking just wana see some bents with propulsion

My gut feel is you can leave it in Eco. Otherwise known as twenty years younger. Next setting is twenty years old. And sport is you liar, you never beat lance;-) The assist will reduce the sting of the hills, you get to the top fresher and recover quicker. It allows me to keep up with the young...

Any bike will do your 5 mile commute. But v bakes do suffer from reduced efficiency in the wet. Long term they wear out the rims, and bikes do do big milages. Disk are much better in the wet and don't need as much maintenance. Improved feel is something for better riders than me ;-)
