Unrestricted Battery Bike

[informer]

A friend has just bought a Black Hawk electric mountain bike. It goes 15mph
but he has been told it can go 22mph if he unrestricts it. Anyone heard of
this or how its done please.

Thanks

First you need to make sure your driving license covers you for mopeds.
Then you need to tax and insure it.
Then you do the technical stuff.

Oh, that might have just answered my question about this bolt on 48cc
petrol motor for MTBs, it was a long shot, but I was hoping it might
just fall outside of requiring tax, insurance and a helmet. Guess
not.

Which is may prove impossible as it may not meet the C&U regulations for a
moped, and thus won't be issued with a license plate.

Having got license plate, tax and insurance (also fun, I bet the insurance
brokers don't have an instant policy ready for it), one also needs a
motorcycle crash helmet when riding it, and it is subject to the road
traffic laws for a motorcycle. So, its not permitted on a bridleway or in a
cycle lane(*), must have an MOT every year, be taxed, insured, etc..


> Then you do the technical stuff.

Which is comparatively simple.


(* it may be permitted in a bus lane, subject to local signposts, which
varies randomly between adjacent towns).

if it's unrestricted it will not be legal as a "electric bike" i'm not
sure that if unrestriced it would count as a moped but may just be
illegal.

by way the bike is this.

there may well be simple limiter somewhere.

Bolt on the engine and you have a motorbike obliging you to have it
inspected and registered as a motorised vehicle before you even consider the
MOT/insurance/VED aspects

There's also the health and safety issue regarding the unprotected chain run
from the engine amongst other things. There's plenty of scope for maiming
yourself. Did you also notice that there's no mention of a gearbox/gears? I
don't think that it will be very adept at climbing hills.

You can buy a cheap moped for the same price.

It's called pedalling. Hope this helps.

Have you seen the weight of them? 38kg! Pedalling isn't going to help
though gravity might if the rider's going downhill.

"Only"?? Is that really 38kg, as in 84lbs?????? Has to be a typo, surely?

That needs to be one hell of a battery to get that thing moving.

38Kg. My god, your legs might not get fit, but your arms sure would.

Unless he's only using it off-road, which is, at least in theory, possible.
Some mountain bikes are used that way, only travelling on the road on a rack
on a car. (But I don't know how to disable the limiter.)

He only got it to go off road. He visits my father and cycles down a dirt
path down the back of a farmers field to get there. Its about 2 miles in
all. He just wondered if he could go faster and how to modify it so he could
get the 22mph he heard it could do

I bet that does "interesting" thing to battery capacity
and/or life.

It's done by removing / bypassing the speed limiter circuit as required by
(inconsistent) EU regulations.
For example : http://www.50cycles.com/torq_spec.shtml quote "15.5 mph
(UK legal limit) Can be derestricted to reach 22mph"
22mph isn't really that impressive for an electric bike considering the
weight most of them are carrying.
If you are interested in non-legal electric bikes (or cyclemotors for that
matter) then the rump of the NACC site might be of help
www.users.globalnet.co.uk/~pattle/nacc I belive somewhere on there is a
horror story of someone attempting to get a motorised mountain bike
registered!

Oh! and if you are interested in derestricting an electric bike - don't
play near me unless you uprate the brakes as well........

That site's not really the NACC's any more - the NACC is slowly falling
apart under the weight of childish bickering.

Is that why I never got a reply to my e-mail about getting a dating
certificate for a cyclemaster?

Is that actually the case? I must admit to being oblivious to the laws
regarding electric bikes, however I was under the impression that so
long as it was considered "electrically assisted" and not electrically
powered (the difference being that it can be used perfectly well
without the electric power to be classified as assisted) it was exempt
from regulation. I had considered modifying a mountain board I have
for electric use to get me to the office from the train, its only a
10min walk but that 10 min walk means I need to get an hour earlier
train to get in on time and I fancy a lie in some days! Linkies to the
law would be nice!

DfT Factsheet - Electrically Assisted Pedal Cycles (EAPCs) in Great
Britain

"The electric motor must not be able to propel the machine
when it is travelling at more than 15mph."

"Maximum kerbside weight (not including rider) shall not exceed -
bicycle - 40kg"

"Maximum continuous rated power output of the motor shall not exceed -
bicycle - 0,2kW"

"A vehicle is not exempt from ECWVTA or MSVA if it is fitted with pedals
and a motor that can provide power assistance at any time without the
rider pedalling"
