Hi All,

I am looking for an engineer to do a piece of work for me to provide me with a report detailing the relevant elements of EPAC tricycle law to a UK manaufacturer.

Essentially I am about to launch a UK manufactured EPAC cargo trike and I need to be 100% sure that I meet all of the required standards. I had posted previously with a similar request and whilst the information given was great, a forum posy it is not something that I could present to an insurer in order to underwrite tens of thousands of pounds of product!
I am not one for taking 'you should be okay' for an answer on a big investment.

I am fairly happy that I meet the UK EPAC criteria for trikes but what I am not sure about is the standards for structural load testing etc I.e. are there any structural testing requirements for these trikes?

From my research and from contacting various agencies, the only standards that I can see I legally have to comply with are the EU EPAC guidelines

Standards | CTC
EAPC Regulations | CTC

I have been in dialogue with the UK CTC technical officer Chris Juden who gave me the following response.

There are tests for bicycles, as part of the EN standards they usually claim to conform to (but no longer strictly have to conform to in order to be sold), but those tests may or may not be appropriate for tricycles, which are subject to different stresses, especially sideways bending and twisting, on account of standing on three wheels rather than being nicely balanced on two.

Tricycles sell in too small numbers for anyone to have gone to the trouble of authenticating a testing regime.

I am about to import a significant quantity of these bikes OR have a significant quantity of these bikes made here in the UK, Hence what I am after is a report written by an engineer giving;
a) Confirmation that the standards listed on the CTC links above are the only legal requirements for selling these trikes in the UK
b) Confirmation that there are not any other standards that I need to comply with in order to sell these bikes in the UK – e.g. structural etc
c) A written report detailing this that I can use if ever I am questioned by a)my insurer, b) someone else’s insurer/lawyer etc.
d) An understanding of how the law might differentiate between the unladen weight of the cycle (58kg when law is 60kg max) and its weight with accessories fitted. For example. I have just sold a bike with a 50kg Ice Cream freezer on the front. When would this freezer be considered part of the trikes weight? Is it considered to be cargo or part of the bike (which would then make the bike non road legal). How can I get around the law if this is the case – i.e. make it removable, nonattached. This applies to all sorts of applications like beer trikes, coffee trikes etc.

My trikes seem to meet the EAPC guidelines for tricycles and also the pedal cycles guidelines – i.e.;
• They weigh less than 60kg (58kg) including battery
• They have 3 x brakes + handbrake, brakes are on the correct side of the handlebars
• They have a label fitted stating motor wattage + speed limitation
• The motor’s maximum speed is 15mph
• The motors wattage is 250W
• They have reflectors in the right places
They have twist and go but no hall effect sensor so apparently are okay for UK but not EU?
• Power to motor is cut when brakes are applied


Again - I am looking for a solid and complete study here from a qualified person and am willing to pay for it.

Any takers???

Cheers

I would try to find/get insurance as a prospective business using the cycles or a rival brands if you plan to market them. While they might be legal many wouldn't go within a mile of the idea if staff are left uninsured using them.

I would also test the rims/spokes as loading up a fridge and adding a rider then asking a bike to do 15mph is a recipe for disasters imo, one fails and ok it was a fluke but a fleet of them and the returns gets nasty. The cargo bikes I have seen tended to have 24" 48 hole rims and not 36s like most motors.

Also you mention 3 brakes+handbrake but surely they can only use 2? I would think very seriously about the idea of giving an average fitness 14 stone bloke one filled with 10kg or so of ice creams and then seeing if they can safely stop. Someone will do it as everyone loves to be rough on 'works gear'.

Would be happy to road test one in London for you. Conveniently I'm about 14 stone and like ice cream.

• They have a label fitted stating motor wattage + speed limitation
Can't help on the vacancy, but have these comments.

Under the UK's EAPC regulation the label should state the motor wattage, the battery voltage and the trike's weight. In addition the label should be fastened onto the trike where it can easily be seen and read.

Only two brakes are required, though a handbrake is a sensible addition on a cargo trike.

If the freezer was merely being carried to a destination the law would not trouble you. However, if it was in use on the trike to either trade from or to carry frozen supplies to a destination, you would definitely fall foul of the law.

Thanks for the info guys! I am struggling to imagine what happens when you eat too much ice cream... probably not nice...!

I will/have contacted Alan Cater - whats his background?

RE trike V-brakes - I have done the maths, In my ten mile daily drive I carry a big 40kg dog, two kids, beach+school gear, me (90kg) and the bike (60kg) - its easily over 250kg.
I have been doing this for six months now on steep hills, in the wet etc. I have had no problems whatsoever, it allways pulls up quickly and I have never experienced brake fade or disintegration.

The handbrake is just a lock on the rear lever, so I only have two levers.

I will check out the rear hub spoke holes issues - cheers!

Hi

Alan is the Technical liaison at the bicycle association. He is very knowledgeable and sits on all the bicycle technical meetings here and abroad.

Good luck!
