Custom electric bicycle builds (DIY)

It depends. I sleep in metropolis, a sport friendly town. I actually have a Stromer ST1x that if I provides a correct go, will reach up to fifty kilometre per hour. I puchased it at a good electrical bike startup referred to as Quantum eBikes, QUANTUMEBIKES

When I take a look at drove it on the bike path (they have a right away access to one), I might tell that if i actually needed to, I might become a demon hehe.

I guess it depends on the person, really.

They say they've got an exclusive contract with MIT for the technology and rights to produce Copenhagen Wheels

It's a 350 watt (or 250 watt in the EU) electric bicycle hub motor design. It has a built-in 48 volt battery pack, but don't give the amp-hours capacity. The range is said to be 31 miles. It supports regenerative features. It's available in either 26 inch or 700 cm wheel sizes. It works with both single speed and 9/10 speed hubs.

When installing a GEARED front hub motor that has no markings or directions is there a specific that it should run? I just purchased a 250W DC Permanent Magnet Brushless Geared Motor. It's sold as a QQ- m100 or m100 or sometimes a Cute 100. It uses a small no name controller. The controller wire identification chart does mention reversing 2 of the Hall sensor wires if it runs the wrong way. I installed it with the wires coming out of the L/S of the hub.

I put this E-bike kit on my trek. it's about a year old and is already loosing its battery life and some of it's speed. I'm joining this forum to get direct help into maintaining it better. and possible getting some more speed. 35kph would be ideal.

can u help??? the moter on this scooter bike is hard to start off from the revs,when on the stand a rev and u can here the moter kicking in and out, once i start to peddle for a while it stays on, is there brushes in these??

Being with no license because of disability, this bike has saved me for a flawless 1.5 years of no bus, until a recent no start problem (below). I was crushed when I heard that the company was out of business because the bike has run flawless, and I have every tool there is both mechanical and electrical if it is something that was fixable by me. (I found after reading through that someone had Ricks email, so I did email one of prv techs, ric.ruggiero [at] yahoo.com).

I have a BMS to use for a set of 16 Headways I got for my e-bicyle. The BMS and Battery pack are separated, and I want to be able to take the battery pack off and leave the BMS on (pack is in the frame, BMS is on a back rack). So, I need some kind of connector inbetween the 17 22ga wires wire coming off each battery to the BMS.

I'm new here and I (hopefully) have inserted an image of an E-bike which I have picked up and hope to modify to a tilting trike by fitting 2x electric wheels on the rear - at 16",they are smaller than the original bicycle wheel, but otherwise look identical.
I would like to know the make and age of the machine which has no identification markings whatsoever, but I'm hoping that someone can recognise it and tell me more.

I wanted to run the motor through the bicycle gearing system including the front chainring set. Got it done, but plenty of concept and engineering work went into the bottom bracket arrangement. Anyway, here it is for anyone interested: Youtube videos

Goveck has 4 bikes, mainly a
light version of $4000 that goes 15-27MPH,
medium with Li Ion battery for $5000 goes 15-27MPH,
and a heavy one for $8000 that goes 60MPH.
and a carrier design.

They're quite expensive indeed.

Emco has a good 5 types of bikes,all kinds of styles.
