That's very interesting, what size battery do you use with it and where did you mount it ?

I started with a 48v 14Ah, now I have two 20Ah ones (one at a time) because I'm planning some long rides next year. They all fit easily in the triangle.

Does 2* 48v 20ah batteries affect the handling or the suspension? Where do you mount them both?

That must give a huge range

I only have one ftted at a time. I'll be using a single-wheeled trailer for the second one on my long journey.

You could go on a 100+mile 5 day camping trip somewhere scenic, covering a leisurely 20 miles a day. Hope there'll be a [mention=34503]matthewslack[/mention]-style photo thread. I was thinking of doing something similar sometime between a series of comfy, cheap, tick-free (but bedbug infested) AirBnBs.

I don't find mountain bike very good for long rides on road which is why I was looking at the rigid fork hybrid range.

15mph on slightly bumpy uneven roads can be SCARY on a rigid bike with no suspension. and having to moderate your speed to 8-10mph or take an active stance on your bike just to potter along local side streets will make you want suspension let me tell ya

I've done both and hasn't been my experience.

Depends a lot on tyre style, size and pressure, but I don't feel I've benefited much from suspension.

I can ride my road bike for about 4 hrs without suffering too bad as long as I wear padded knickers. I think the reason for that long is the riding position and hard pedalling lifts a lot of weight off the seat, plus frequent standing on the pedals gives your bum a chance to recover. It's a different story on a commuter bike. I tried various types, but they all became uncomfortable after about an hour until I got air suspension. Without it, every small bump becomes increasingly more painful with every minute. The idea of the motor is to make easier pedalling so that you're not knackered and sweaty when you get to work, but that means sitting in the saddle for a long time., which is what gets your bum.

Well it came as a HUGE surprise to me when i first turned off the nice smooth cycle track onto the local roads at circa 15mph (totally unpopulated track n road Vast visibility too thankfully) Under ebike power,

with my full mass sat firmly and comfortably in the saddle, my legs adding little to movement. hey 1st trip out on my ebike..

 

Totally different experience from gaining similar momentum under my own steam, as it turns out 15-16 mph is a full out pedal in top gear on my ol boneshaker something i have often achieved on these roads, but am taking a much more active role when doing so most if not all my mass supported by my legs to build up the required speed. like this the bumps and cracks in the rd are absorbed by my legs..

 

But when sat firmly in the saddle all the force is directed right up the spine and its sure enough to lift me clear of both pedals.. And that came as a HUGE shock. Not to mention watching all the shopping launch itself out of boxes front and rear Tins of pop bursting on the rd .. not fun..

 

Now granted my inexperience on an e-bike played a major factor, And Ive been significantly more cautious since, but this was a route i had ridden on a cycle on and off for over 50 yrs .

That Rocky Mountain Element + Bafang BBS01 would make an excellent e-bike with some cash to spare.

Do you know if the bottom bracket on those Rocky Mountain Elements is compatible with a BBS01 / 02 ? As [mention=3847]saneagle[/mention] says, for a mid drive it's probably worth finding a steel replacement cassette (and maybe ebike grade chain)

They have standard bottom bracket.

From the pictures, that bike has hollowtech II bottom bracket so it is compatible with Bafang BBS01/02.

Hi all,

 

Just wanted to thank you all for your input and advice and let you you know what I decided in the end (nothing worse than an unresolved thread lol)

 

I decided in the end to go for a prebuilt ebike and chose the woosh camino.

 

Main reason was I just couldn't seem to find the right donor bike and I realised in the end I probably want an ebike and a good non assist bike and I was trying to find one solution that solved both which is not possible.

 

So I've done my first commute to work yesterday on the camino and it ran like a charm. Meant I could coast to work in the morning and arrive sweat free and then pedal home for some exercise.

 

Only thing I thing I noticed was a slight stickiness and a bit if a whistle from the front wheel so assuming I need to adjust the front brake disc which I've never done so that will be a learning experience.

 

Did have a final question though. Where and how does everyone store their ebikes, especially with winter approaching? I have a garage but it's not the most weather tight and being up north the temperatures can get pretty low. Is it safe to store the bike and battery in the house overnight long term or do people have other solutions?

 

Thanks

The front disc brakes are hydraulic. If you feel any binding, take a look at the caliper. You want the rotor to be centered between the pads.

If it's not centered, loosen the front quick release skewer a turn, squeeze the front brake lever, tighten the quick release and release the brake lever. Check again that the rotor is now centered.

The brakes will then on automatically adjust themselves.

0-35 ℃

 

The ideal operating temperature level for lithium batteries is 0-35 ℃. The low-temperature conditions will decrease the lithium ions' activity causing the LiPO battery discharge capacity to be weaker, and the usage time is reduced

 

cheers google..

 

Keep the battery in the house when temps start to fall below 5c at night to be on the safe side.

 

 

if ridding in the colder weather a 'cozy' might be an idea worth looking into

Storage temperature : the range is wider, from minus 20C to 40C so no need to bring the battery indoors.

I am no expert i rely on my ability to cut and paste into a search engine, so not doubting the correction.

 

However what if your jumping on the bike early morning for a ride into work after a sub zero night?

 

Wouldn't it be better to keep the battery within operating temps?

You lose some voltage, so some capacity but the battery won't die from cold.

Cheers, I will shut up now get my coat and skulk home..

On the flip side of this though would there be any issue in keeping it indoors overnight?

no, but there is always a tiny risk of battery fire. If you do take the battery indoors, keep it in a ventilated place to vent any eventual smoke. To minimise fire risk, unplug the charger after charging is finished.

It's a good habit to keep a log book to record mileage and date/time of charges. Allow 6 minutes per mile, so you know when charging is expected to be complete.

me leave? nah,,

Is that a better gauge than using the battery% and battery size to determine the charge required, ie 50% 11ah battery would require circa 5.5ah to charge up from a 2a charger, should take about 2 and 3/4 hrs to charge fully.

I ask because i am using battery% as reported by my controller headset as my charge duration guide and set a segment timer accordingly, I didn't look it up it just seemed obvious.

2A charger: 6 minutes per mile

3A charger: 4 minutes per mile

4A charger: 3 minutes per mile

 

This rule allows enough time for balancing at the end of the charging period so it minimises fire risk.

Fire risk increases kind of exponentially with high current charging so best avoided unless your charger can get the temperature reading / talk to the BMS.

Are there devices that you can run your charger through while charging the battery that allow you to set a charging limit? Sure I saw someone say this and you van set it to stop at 80% charge for example?

there are special chargers that let you do that. They have presettable lower charging voltage likle 40V to prepare the battery for long storage period. Your battery does not need to be prepared for storage.
