how easy is it to make an E bike out of a conversion kit?

[Alan Quay]

For reference, my current main bike setup is:
Q128 motor, fwd
500w controller
20ah 36v BMS shrink wrap battery, on rear rack.
Me:18st, pedaling moderately hard.
Cruise at about 18-20mph
Range approx 40 miles on flat - moderate terrain.

Unfortunately Bayrider we don't have a kit that comes within your budget, but you can download the eZee kit installation guide from our website here eZee Downloads - electric bikes and conversion kits and the Ansmann You tube assembly videos here YouTube Videos - electric bikes and conversion kits.

Hopefully they will give you some idea of what is involved.

He will definitely get a very good and helpful idea with those good videos of yours.

I don't think a 10ah battery will be man enough for the BPM/CST 500 watt motors, Rob.

I have an 8fun kit fitted to a Carrera Kraken & it's ok if you put a fair bit of effort in yourself, but the bottle battery, which is 8.8ah, is showing serious symptoms of impending doom & it's only 15 months old.

Conversely, I've just fitted one of Cyclezee mk2 kits to my new Trek Mamba & it's in another class altogether: I've only done about 200 miles on it in the couple of weeks I've had it, but it's been a real revelation - This is what an assisted bike Should be

Problem is... Price: As Cyclezee says, it's close to a grand - half of which is the cost of the 14ah battery

Personally, I decided to deal with a supplier I trust (& I know where he lives ) but you can save a lot of cash buying direct from China & foregoing any warranty or support, other than that of the knowledgable & extremely helpful guys on here.

Don't expect 18-20 mph from any of the lower-powered kits or bikes: In fact, without considerable input from me, my 8fun wouldn't pull Granny off the pot

The Cyclezee is a different matter altogether, despite also being only 250 watt ... Yeah, Right! And the 500w Bafangs are... 500 watts.

If you opt for a bottle battery then you need to be confident that it will fit in the frame triangle and have the right capacity. If you go for a rack option then research thoroughly and look at the options on here, especially d8veh's solution. I'm on my third rack now! Two broke due to bouncing kerbs and the Panasonic battery housing has now self destructed..... This means that the battery is permanently fixed to the bike and has to be charged in situ.

You can get a 250w version of the 500w Bafang. I have one on my bike. You get real torque from it with a 30 amp controller and 48v battery. The Ezee is 20 amps from a 36v battery, which is enough for most people.

d8veh constant:

I x V = 250

I'm gonna get some stickers printed up with the constant printed on them, just incase I forget. Probably keep one on my bike somewhere

Might have to stick one on this thread too.

 

[cwah]

I don't see your point mike

 

[Alan Quay]

I don't see your point mike

d8veh has pointed out (quite rightly) that the sticker on the motor is not relevant to the power. The power is governed by the voltage (battery) and current (controller).

The sticker is only relevant when the glue melts and centrifugal force sends it flying.

Hi d8veh

thank's for that info where can I obtain those items and what battery would I require

 

[Deleted member 4366]

I don't see your point mike

You need the same label on your motor, Cwah. Check the current from your controller (say 25 amps), then check your battery (say 60v), and then you need a label that says "36v 250w". If you ask nicely and order enough motors, the motor supplier will normally engrave it on the motor for you, as many well-known bike manufacturers found out. I think Bosch started it, but maybe Ezee was ahead of them.

 

[cwah]

aaaah... ok lol

I don't think anyone would care in France. lol

Never been checked on my bike "legality"

That wasn't meant to be taken too seriously. Look at my last post. If you want a powerful bike, there's loads of places to buy the stuff, but I tend to use BMSBattery. You can also double the power by fitting a front and rear motor with say a bottle battery kit on the front and a rack battery kit on the back.

eZee also have a 48v battery which boosts power, one of the eZee conversions that was stolen recently had one and the owner is left with nothing but a charger and a set of keys

That's a real bummer, he must be gutted.

I guess ebikes are going to be targeted more often, now that they no longer look like they're based on "Granny bikes".

Mine's a lovely looking bike, so I've made sure it's insured, kept in my locked garage & secured with a Squire Hammerhead, Sold Secure Gold D-lock, with a cable thro' the front (Q/R) wheel when I'm out & about.

And I live in a Low-Crime area

 

[jerrysimon]

I shouldn't jest, I know I would be gutted if my Bromptons were stolen

Hi Pete,

Yes he is seriously gutted.

It was stolen from a railway station in Hertfordshire.

I don't know what security he had, but it was parked their on regular basis and someone may have planned to steal it rather than an opportunist.

If I park at a railway station, I use my trusty old Quando with an old battery, no one would look twice at it.

Hi the lock we recommend to our customers Is the Oxford revolver Not that heavy BUT it is A thatcham approved Motorcycle Lock

My brother-in-law has just had a cycle stolen from Cardiff railway station, and it even had two £50.00 locks fitted! I have no idea what he secured it too, but the locks were worth more than the bike.
There is some worthless scum out there.

I'm only assuming that my bike is covered on household insurance, but this thread has brompted me that it is something that I should look into.

You need to consider your long term intentions with this bike conversion. If they are to use it as a commuting work horse, you would be wise to invest more in decent quality kit, especially a kit which comes with a good battery.

Keep in mind that there are no bargains and that to buy cheap usually involves buying twice. You could end up suffering two cheap kits / batteries when you could have been enjoying one very capable quality kit for the same price.

I have no affiliation with any particular brand.

for commuting, the BBS01 kit is difficult to beat.
